Hi JuhiMiki

So, simply put, 709 is the standard (SDR) and most content that people are consuming in HDR is going to be DCI-P3. On the other hand, 2020 is basically a signal that tells the display to go as wide and full as it can (in terms of colors). In other words, it’s considered to be the limits of the TVs color capabilities. In this case, I don’t think you could say that one is better than the other though, they all have their own advantages and disadvantages.

For the Gammas, 1886 is considered to be the ‘standard’ and is actually closer to 2.4 than to 2.2, which is what we recommend. This is because it would be best in a theatre environment (super dark) so it can make the image very movie-like. That said, a lot of people may not have that environment, so 2.2 would likely be better in those cases. Also, 2084 is an HDR standard for gamma and it’s rated to go all the way up to 10000 nits. It’s usually used to manipulate the gammas on a TV.

If you have any other questions, do not hesitate to reach out!
