> I do not own any HiDPI monitors

This is a major factor. macOS has aggressively optimized for these in recent years, often at the expense of classic 1x display experience. I use 5K 27" and 4K 24" monitors at 2x scaling (this is the default), and the result is excellent.

Maybe so, but the blurriness caused by decisions around antialiasing and hinting was present already in Snow Leopard, which predates the first retina Mac.
