What is the popularity of screens with high dpi in RuNet and in the world?

Question

Screen resolution

I'm interested in how popular high density screens are.
What density how many percent?
I would just google permission statistics and figure it out, but such statistics are misleading.
For example, my monitor (retina) is defined as 1280x800 through screen.width/height, but in fact I have twice the resolution. Many modern windows laptops with high dpi are also detected erroneously. Because of what, it seems to me that googling statistics are lying -

Maybe someone found something similar? Or measured on their resources?
