I absolutely benefit from a 4k screen even in a small form factor. 768p is "enough" in the sense that we all got stuff done on such screens for many years, but the increase in text rendering quality with higher PPI screens is tremendously worth it to me for the reduced eyestrain. 4k is still noticeably better than 1440p. I wouldn't be surprised if 8k is noticeably better still (although with swiftly diminishing returns of course).

The reverse is also kinda true... Many people when they say "I like high resolution" mean "I like to fit lots of stuff on the screen at once".

If you're in the latter crowd, you can configure X or Wayland to render to a 4k screen buffer, and then downscale to fit the actual screen. Yes, downscaling no longer means 1 pixel=1 pixel, which introduces some blur, but unless you're a 20/20 vision kind of person, I doubt you'd be able to tell without your nose touching the screen...
