The Samsung CU7000 has an okay color gamut. It has good coverage of the DCI-P3 color space, which is the most common color space for HDR content. Its colors are generally undersaturated, and its tone mapping isn’t accurate except for saturated colors and, to a lesser degree, very lightly saturated ones. The TV’s coverage of the Rec. 2020 color space is inadequate, so it’s not future-proof, as Rec. 2020 will become more prevalent with time.
