I think we're not very close. This discussion is about a 162 dpi display, so quadrupling that to 648 or quadrupling on two dimensions gets us to 2592 dpi. That's the right ballpark [1], but only on iPhone-sized devices. The iPad is 132 dpi [2], about 10% better than a typical CRT from a decade ago [3]. MacBook Pros recently got the first resolution increase (36%, to about 115 dpi) in about 5 years. At that rate it will be more than 20 years before we reach the limits of human visual perception on large displays.
