I agree 4k in each eye sounds insane. But eye strain that's going to be the big determinant. I initially thought it was transparent OLED at the start but to my disappointment it's just screens. Perhaps they've got the focal adjustment thing Magic Leap was trying to do right.
4K is not much if you consider that these pixels have to cover the entire field of view, not just a relatively small screen.
It’s certainly a generational jump from the Quest series at least. Of course the price is completely ridiculous
The best an eye can discern is roughly 20 microns, but generally far higher at 100 microns. They said 7.5 microns per pixel (X3 for RGB is 22.5 so roughly there without space).
Assuming they're square. Roughly calculating (23 million pixels between the two with no space between 7.5 microns,) that's 25.432mm^2. they've said they're the size of postage stamps. This ties in.
I think it's near safe to assume there's no real gap between pixels and thus indiscernible. The lag might be a thing and focus, but this might actually not be a problem.

The size of an object doesn't matter. What matters is how it gets projected onto the back of your eyes.
There are 120 million rods (black and white) and 6 million cones (color) in a single eye. You would need at least as many pixels. But photoreceptors are not evenly distributed, so to account for moving your eyes across the screen, you would have to have even more pixels.

The pixels may be 7.5 microns but you’re forgetting that they are viewed through a lens. The point stands: 4K pixels for the full field of view, which is a lower density than 4K for a small screen.

That's not how it works. You need an angular resolution.
