I have both side by side and i think this is more of a myth. They simply render the same on hidipi except very small sizes where the engines differ.
On Linux font selection is terrible, people have problems with Wayland/x11 rendering and other settings (often opinionated defaults from distros).
But when you are lucky :)) you can get pretty much same hidpi font rendering.
Freetype at least has knobs that are both configurable and understandable. On Windows, you only have Cleartype Tuner, and it can be hard to get what you want.
