This compression failure is also not simply the result of how big or small the gamut is.
I have SDR displays using a p3 and rec2020 lut, It's only 76% dci p3 and yet NO Posterization.
Smaster's observation of getting posterization tuning for rec2020 is TRUE for HIS DISPLAY. It is NOT_TRUE for all displays. Again, it's not due to how big the gamut is, it's how closely aligned the primaries are to the source color space, and the various interplays of the display chain. We have multiple devices with multiple maps.

Yeah I read that it may do like 80% of 2020 vs almost 100% for DCI P3.
So if if it was you, how would you calibrate it for 4k movies?
