Samsung MU7000 DCI-P3 or BT.2020?

Hi there, I own a Samsung 65" MU7000, and I have a question about how to set the correct color space for HDR material. All of the documentation I've read for setting the TV to watch movies is to switch the TV to HDR Movie mode. However, when I do this, the default color space is set to DCI-P3, and not BT.2020. I would think that leaving this setting as default would be the correct option, but often when I watch HDR movies, the colors look too saturated, especially with the amount of red being added to skin tones. Sometimes faces end up looking incredibly pink, especially if they are out of focus in the background. I think things look better when I switch the color space to be BT.2020, but I am worried I am desaturating the colors too much. I know that pretty much all content is mastered in DCI-P3 and then put in a BT.2020 wrapper, so I am not sure if it is correct for me to switch the color space to BT.2020 instead of using the default DCI-P3. I mean, it makes sense to me that if the 4k blu-ray is outputting a bt.2020 signal, I should set my TV to bt.2020, but it's just confusing how it uses DCI-P3 as the default. I know something is not working right, because I have compared some films with their HD blu-ray counterparts, and the skin tones don't look nearly as pink in rec.709 (I know rec.709 is a smaller color space, but the skin tones shouldn't deviate that much...). Anyway, I'm hoping someone can put my mind at ease that I am using the correct color space on my TV!

Match the color space to this original source.


Sdr = 709

Hdr = DciP3.

Very much if you have a AV receiver you can check the file information. 4k UHD bluray signals are BT 2020, so would advise to leave the color space settings on auto format. If you don't see an auto for HDR, then BT 2020 is best as this is container in which carries the signals.

Wrong. The container is bt2020 but P3 is what is actually used. Having a Samsung TV, I can tell you 100% the correct setting is P3 because 2020 washes out the colors.
