BT.2020 container can be carried by either.

And from the link...

To get the video displayed on the TV or Projector it typically goes through the following conversions:

4:2:0 to 4:2:2
then 4:2:2 to 4:4:4
then Y’CbCr to RGB

Thank you, i ask this because one of my processor settings has a choice between YCrCb2020 and RGB2020, sounds like YCrCb2020 would be more common in TV and in movies
I use auto setting for now, but eventually i can input the correct setting, possibly improving performance
