Oh bad question is it? Then why is it measured? It is infact a relevant metric for HDR, just like peak brightness. While peak brightness measures the intensity of "whites", color volume measures how bright/saturated individual colors on screen can look in HDR. Currently HDR content uses DCI-P3 in a Rec 2020 container, and not the entire Rec 2020 space, so the higher coverage of DCI-P3, the better. And the question I asked was related to oled. Among oleds, which tv is able to put out the highest color volume? I don't think you answered that. Based on seeing the measurements posted online, it seems to be the sony A9F, but is there anything better?
