It's progress...of course, but almost no-one really needs 8k as they sit too far away to notice.

again, its related to the screen size. at 85in and above, you will notice even if not close. outside the fact we were sitting far away from tvs because of low res of fhd on screens above 49in. fhd requires at least 3 to 4 times the screen height as min distance, when 4k requires 1 to 1,5 times.
