It is closer to 16K. In terms of PPI limit the Apple Vision Pro does ~3300 PPI. For it to hit perception PPI I remember we need close to 1000 PPI at same distance for it to fit PPD close to 100.

So I say in terms of those limit we need another 10 years. Which is also why I think the Vision Pro was 2 - 3 years too early. But then Modern Apple has the cash flow to continue to fund it.
