Musings on discernible display resolution (color and geometry) (part 2)

Something that I think is often overlooked: Some think that it's a total waste if you sit so far from a 4K 2160p display that 4 pixels effectively blend into 1 pixel, as far as the eye is concerned. So in essence it becomes a 2K 1080p display.

That's not the whole story.

Those 4 pixels color average, and that color averaging effectively quadruples the color depth. So instead of a 2160p 24bit color display, you now have a 1080p 30bit color display, and that's not too shabby from where I'm sitting (pun intended! ) Same idea with 8K: Imagine a 4320p 24bit color display, sit too far from that and it effectively becomes a 2160p 30bit color display. Sit even farther and it become a 1080p 36bit color display.

As you can see quadrupling the pixel resolution will quadruple the color resolution for those whom sit far away from the display. Correct me if I'm wrong, but 24->30 and 30->36 are both quadrupling, adding 2 bits to each of the 3 primary colors. It's still better to sit close and see all of the pixels, I'm just suggesting that it isn't a total loss sitting far from the display.

You could have 1 bit per primary color per pixel and that would suffice if you had an enormous number of pixels giving you full res and full color depth that the eye can discern. Not practical of course, but just for illustrative purposes.
