Detail, and the number of pixels in a display needed to achieve that detail, are very much "relative", with the distance from our eyes to the display being the critical part. A "4K" display is 3840 pixels (dots) across and 2160 pixels high. Your comment "sharper than what our own eyes can perceive" is only true if you put a 4K display that is, say 55 or 65 inches diagonal (the typical sizes of the LCD sets available from Sony and others today) eight or ten feet or more away from where you sit (which, in fact, IS what most people still do with their TV sets, even HD sets). A 4K display is only worthwhile if you either:
1) Set it up so you sit VERY close to it if it is a 55-65 inch display (I mean, put it on a dining room table as if it were the centerpiece and sit "at" the table, or similar-it needs to be THAT close to see the difference from a non-4K display!), or
2) If you plan to sit at a traditional "living room watching distance" (ten feet away or more from the screen), you get a projector and a BIG screen, I mean ten FEET diagonal (120 inches) or even bigger.
The point of all this is, 4K TV sets are overkill for most people.
