It's the point where I think we can pretty much say, okay, we are now finished with resolution increases. There's nowhere else to go. We've 100%'d that part of the tech tree. Weirdly satisfying.
Seeing the film grain detail on older movies is strangely satisfying to me. Even newer movies shot digitally are done so at 2K or 4K.

I think it has something to do with full vision of the screen at any time so your its centerted and a particular percentage of your field of vision. I couldnt find the study which was for sports and movie watching but I bet such a standard is even more important for gaming.
Basically relatively speaking your screen should be the same size in your field of view but the fact that its bigger allows for better detailing.
4000px from 5 feet doesnt look at good as 8000px from 10 feet even thought they fill up the same area in your field of view
