AFAIK, both Windows and MasOS allow you to rescale your windows and their contents to be bigger. This is a smart zoom that doesn't simply upsize every pixel on the display. So high density displays should no longer require squinting for us folks over 40.
Seeing more or having more open at once is beneficial, but so is comfort.
I bought it in 2018, but only recently I have found my 28" 4K is too small at 100% scaling. I think it is roughly the same distance away, but I'm not going to be uncomfortable, so I scale it to 125% now.
I've also found this more necessary later in the day vs when I just woke up.
Same thing ui designers. Thats why I resize all the fonts on the page. The probably negates all the UI designers attempts to make the audience go blind
