The hardware is great, but the software is lacking. macOS only supports resolution-based scaling which makes anything but the default 200% pixel scaling mode look bad. For example, with a 27" 4K display many users will want to use 150% or 175% scaling to get enough real estate, but the image will look blurry because macOS renders at a higher resolution and then downscales to the 4K resolution of the screen. Both Wind…
This is correct and also increasingly affecting me as my eyes age. I had to give my Studio Display to my wife because my eyes can't focus at a reasonable distance anymore, and if I moved back further the text was too small to read. I ran the 5K Studio Display at 4K scaled for a bit but it was noticeably blurry. This would've been easily solved with non-integer scaling, if Apple had implemented that. (I now use a comb…
Some indie Mac developers even started implementing support for it in anticipation of it being officially enabled. The code was present in 10.4 through 10.6 and possibly later, although not enabled by default. Apple gave up on the idea sadly and integer scaling is where we are.
Here’s a developer blog from 2006 playing with it:

There was even documentation for getting ready to support resolution independence on Apple’s developer portal at one stage, but I sadly can’t find it today.
Here’s a news post from all the way back in 2004 discussing the in development feature in Mac OS tiger:

Lots of of folks (myself included!) in the Mac software world were really excited for it back then. It would have permitted you to scale the UI to totally arbitrary sizes while maintaining sharpness etc.
