Does 4K UHD Blu-ray support 12-bit color depth?
I’m aware that 4K UHD Blu-rays which have HDR10 supports WCG (Wide Color Gamut) which is 10-bit color depth.
However, 4K Blu-ray titles with Dolby Vision enhancement layer is what confuses me.
They say DV supports “up to” 12-bit color depth.
From my searching, it seems that 12-bit color is used at mastering stage in the studio for DV.
However, it looks like they encode into 10-bit HEVC for 4K blu-rays. This part isn’t clear.
Are DV enhanced blu-ray titles encoded in 10-bit or 12-bit color depth?
