RGBY is a gimmick. The source files are RGB. If the extra yellow data isn't there at has to be made up. So you either just blend the colours and get normal RGB or guess the yellow values and fake in the same bad way every screen at a show room is over saturated.

I can also display upscaled 4k content on my FHD TV...even the guy who physically saw it in person couldn't tell the difference (lol) except for differences in vibrancy (note: vibrancy is not a measure of fidelity). I think resolution above 4k on screens < 60" is a case of diminishing returns. I can barely tell the difference between 720p and 1080p on my 32" at normal vieiwng distance, nevermind something 4 times or 16 times the fidelity of 1080p.

It seems like a game they are playing now.....8k? Seriously? and upscaled?

Do we really need 8k consumer equipment when 4k is way beyond anything most people will ever be able to distinguish on the size screens you will have in a residential property?

There are four primary colours now?
