Their anatta understanding is still inferential, even if they have peak experiences of some aspects of no-self. It is not the same as what we call the realisation of anatman.

It will be good that when doing vipassana, at the same time you contemplate experientially the two stanzas of anatta or bahiya sutta, that will lead to the anatman breakthrough

"Someone asked me about luminosity. I said it is not simply a state of heightened clarity or mindfulness, but like touching the very heart of your being, your reality, your very essence without a shadow of doubt. It is a radiant, shining core of Presence-Awareness, or Existence itself. It is the More Real than Real. It can be from a question of "Who am I?" followed by a sudden realization. And then with further insights you touch the very life, the very heart, of everything. Everything comes alive. First as the innermost 'You', then later when the centerpoint is dropped (seen through -- there is no 'The Center') every 'point' is equally so, every point is A 'center', in every encounter, form, sound and activity."
The Key Towards Pure Knowingness
"The key towards pure knowingness is to bring the taste of presence into the 6 entries and exits. So that what is seen, heard, touched, tasted are pervaded by a deep sense of crystal, radiance and transparency. This requires seeing through the center." - Thusness
What is Luminosity?

DhO questioner: What is Luminosity?
Daniel M. Ingram:
Luminosity is both a useful and possibly very misleading term.
Here's what it is doesn't mean: that a person will suddenly see things more brightly, that there will be more light in things than the standard amount, or anything like that.
Here's what it points to, said a number of equivalent ways:
“1) In the seeing, just the seen. In the hearing, just the heard. In cognition, just the cognized. In feeling, just the felt... This standard line from the Bahiya of the Bark Cloth Sutta in the Udana is one of the most profound there is in the whole of the Pali Canon. It means that sensations are just sensations, simply that, with no knower, doer, be-er (not beer, as that is a beverage), or self in them to be found at all.
2) Point one, taken in its logical inverse, means that the "light" of awareness is in things where they are, including all of the space between/around/through them equally.
3) Said another way, things just are aware/manifest/occurring where they are just as they are, extremely straightforwardly.
Helpful?
Daniel”
We can only perceive the suchness of things through an awareness that opens to them nonconceptually and unconditionally, allowing them to reveal themselves in their as-it-is-ness. As the poet Basho suggests:
From the pine tree
Learn of the pine tree
And from the bamboo
of the bamboo.
Commenting on these lines, the Japanese philosopher Nishitani (1982) explains that Basho does not mean
That we should ‘observe the pine tree carefully.’ Still less does he mean for us to ‘study the pine tree scientifically.’ He means for us to enter the mode of being where the pine tree is the pine tree itself, and the bamboo is the bamboo itself, and from there to look at the pine tree and the bamboo. He calls on us to betake ourselves to the dimension where things become manifest in their suchness. (p. 128)
In the same vein, Zen Master Dogen advises: “You should not restrict yourselves to learning to see water from the viewpoints of human beings alone. Know that you must see water in the way water sees water” (Izutsu, 1972, p. 140). “Seeing water in the way water sees water” means recognizing water in its suchness, free of all concepts that spring from an observing mind standing back from experience.

I also wrote in 2011:
Good insight. Stability of experience has a predictable relationship with
the unfolding and deepening of insights. For example how seamless and
effortless can non-dual experience be, if in the back of one's mind, subtle
views of duality and inherency and tendencies continue to surface and affect
our moment to moment experience - for example conjuring an unchanging source
or mind that results in a perpetual tendency to sink back and referencing
experience back to a source.
For example even after it is seen that everything is a manifestation of
awareness or mind, there might still be subtle tendencies to reference back
to a source, awareness or mind and therefore the transience is not
appreciated in full. Nondual is experienced but one sinks back into
substantial nonduality - there is always a referencing back to a base, an
"awareness" that is nevertheless inseperable from all phenomena.
If one arises the insight that our ideas of an unchanging source, awareness
or mind is just another thought - that there is simply thought after
thought, sight after sight, sound after sound, and there isn't an inherent
or unchanging "awareness", "mind", "source". Non-dual becomes implicit and
effortless when there is the realisation that what awareness, seeing,
hearing really is, is just the seen... The heard... The transience... The
transience itself rolls and knows, no knower or other "awareness" can be
found. Like there is no river apart from flowing, no wind apart from
blowing, each noun implies its verb... Similarly awareness is simply the
process of knowing not separated from the known. Scenery sees, music hears.
Because there is nothing unchanging, independent, ultimate apart from the
transience, there is no more sinking back to a source and instead there is
full comfort resting as the transience itself.
Lastly do continue practicing the intensity of luminosity... When looking at
tennis ball just sense the tennis ball fully.... Without thinking of a
source, background, observer, self. Just the tennis ball as a luminous
light. When breathing... Just the breathe... When seeing scenery, just
sights, shapes and colours - intensely luminous and vivid without an agent
or observer. When hearing music... Sound of bird chirping, the crickets...
Just that - chirp chirp. A zen master noted upon his awakening... When I am
hearing the bell ringing, there is no I and no bell... Just the ringing. The
direct experiencing of no-mind and intensity of luminosity.. This is the
purpose of the practice of the four foundations of mindfulness that is
taught by the Buddha.
