4k would exceed that significantly on a 6" display. Thus why parent compares an 8k phone to the 24/192 discussion - the benefits are nothing more than being able to advertise a larger number.
I kind of had that effect at a trade show a while ago where they had huge demo displays like 12 foot /6000 pixels across and I couldn't see all the detail at a usual viewing distance but could make it out in small areas by wandering up close. It was kinda cool. I'm not sure it would have that much value in a domestic setting but in something like a museum / gallery could be good.
so, carrying that to its logical conclusion, does that mean that at some point we will create displays w/ such a high resolution that they will, in some sense, be creating a "universe" which is indistinguishable from that which they are displaying? or, i guess that would mean the display essentially is what it is displaying. is that even possible in our universe, or would that be akin to creating energy / matter from nothingness?
clearly the display would blink "let there be light"* at startup.
