The problem is the contrast ratios. The contrast between 0% black and 100% white on a good screen is so high, it physically causes pain, even migraines. Which is why on HDR screens, the colors of CSS are actually limited to avoid ever going darker than grey or brighter than grey, and the contrast is still very large.
#000000 on a cheap screen is equivalent to #666666 on an HDR screen, #ffffff on a cheap screen is equivalent to #aaaaaa on an HDR screen.
So if a designer uses something that looks exactly like newspaper contrast to them, it’ll look unreadable on a cheap screen.

Maybe that means you need to turn down your screen's brightness.
It's called sRGB and it supposedly has a "black point" which is not entirely black. Nobody uses it though, on photos it would be useless. Also for me black on white is perfectly fine in a well lit room. White on pitch black is indeed problematic. Anyway, it could be a user/browser preference instead of a designer preference.
Lowering brightness shouldn't distort color-calibration too. You are supposed to match your brightness to the surrounding lighting too.
