3840 x 2160 resolution per eye. 23 million pixels per eye, or, nearly 3x the pixels of a 4k TV with the equivalent resolution. That's roughly 3 physical sub-pixels per 1x1 "virtual pixel".
As well, given the oddities of human vision and how eyes focus, they can give more subpixels to the tiny area your eye is looking at to increase fidelity

That is apples to oranges. The virtual pixels are mapped over your entire field of view where the physical pixels are mapped directly to the 2D surface itself.

Again this is a property of the display system and can not be improved by software. Additionally only one part of the lens (usually near the center) will have the highest PPD. Looking anywhere but the center will have a lower PPD.
