I think lots of fonts actually look worse on hidpi screens, especially on Windows, probably because these fonts were specifically designed for low resolution screens. And most applications use hard-coded fonts that you can't change. Text is maybe a little easier to read on hidpi screens, but it is less aesthetically pleasing. Linux can be made to look good in that respect, but the situation for scaling legacy applications is pretty bad.
