64 pixels in the size of an iPhone screen pixel is pretty crazy, and feels like they might have made the leap in technology to make the screen "disappear". I have a PSVR2, and the screen is very much not disappearing in my mind on that thing.
It's slightly misleading because the panels are only 1 square inch per eye but will be blown up by the optics to whatever the FOV is for that headset. Since the resolution is 4000 PPI, it's comparable to a 4K monitor filling the width of your FOV.
