Very well, in my experience. Apple has been doing what it calls "retina" display for a while now, whereby it keeps the display's actual resolution at a high native level but scales everything it renders so the screen is effectively a lower resolution... but really smooth because of it.

Here's an album with a pair of screenshots from my own 4k display: https://imgur.com/a/7AHZZZv -- the scaled one is how I normally use it.

It's sharp enough but when compared to a native 1x/2x scaling, it still looks blurry, and it's only seen physically for me. Currently I run my M1 MBA at native 2560*1600 (BetterDummy, non hiDpi), and my 27" 4k at native. Set default zoom on chrome to be 125/150%, and VSCode also at "zoomed". I mostly use Chrome and Electron based apps (Spotify), so the increase in text sharpness is worth it. Native apps (Pritunl, etc) UI becomes too small, but again it's worth it for me.
