I have a 65" in my living room, sitting about 7-8 feet back, and 4k is without a question, significantly sharper and an order of magnitude better image than 1080p. Yet the chart would tell me it "isn't worth it". Sorry, the chart is wrong. It is WELL worth it. It doesn't mean I am content with 1080p on this TV, just that I can definitely notice the difference from 1080p to 4k UHD blu ray. Not quite as much with 4k streamed, so perhaps it isn't so much about the number of pixels as it is the quality of the image... ?
In my theater, watching my 150" wide scope, sitting ~13 feet back, going from 1080p to e-shift 4k is, without hesitation, truly a "night and day" difference, and the chart says this should be "worth it". However, I can't pick out an individual pixel in 1080p, let alone 4k from my seat. My eyes can barely pick them out at 3 feet, and while I hit the "20/20" vision with my contacts or glasses, my vision is not terribly good. Sure, I can read the eye chart and get the letters right, but the bottom row is still blurry, even with my glasses or contacts on.
My eyes suck, yet I see a significant improvement with 4k that charts (and some people) will tell you that you would never see. Sorry, I simply don't agree, and that is not based on anything other than personal experience. I see no correlation (at least no direct correlation) between the ability to see individual pixels from your seating distance and your ability to notice a significant difference between 1080p, e-shift, and true 4k, so I personally throw that idea right out the window.
likewise, several people both here in this thread and who witnessed the rs3000/nx9 at Cedia report a noticeable improvement with 8k e-shift. When you get close the pixels get muddy and the image has noise, but nevertheless, they see an improvement at seating distance. I can't disregard that, even if the science of how the eye works vs the size of pixels tells us it is impossible.
Just remember that these things are "guidelines" and not "laws of reality". Let your own eyes decide.
