I just toggled between “P3-1600 nits” and “HDR video (P3-ST 2084)” display mode on my Macbook M1pro to see if it makes any difference.
To my surprise, Apple color pallet in “HDR video (P3-ST 2084)” mode is actually accurate and identical to Quicktime!
Additionally, “Infuse color pallet” also produce different results in “HDR video (P3-ST 2084)” and “P3-1600 nits”. It’s especially noticeable in dark scene.
So it looks like Infuse actually has bug that affect both Infuse & Apple color pallet in the default P3 display mode.
Hope this help Infuse team to identify the root cause.
