As I have said many times when ever there is a discussion on 8K, I wished we had settled on 6K instead. Something above 4K, but not 8K which is practically useless on TV.
Because that is not entirely accurate. It is just in most cases. And now the improvement all went to HDR and Framerate. Which is much more useful, but we missed the opportunity for a Higher Res and forever stuck with 4K when economy of scale meant anything but 4K wont ever be able to compete.
