Incorrect colour being displayed with HEVC 2160P Video Files

I’ve noticed a number of videos most recently, as far as I can tell usually HEVC 2160P content, the colours are usually displaying green or very off normal/natural.
Is this most likely down to the rip, a wrong Vero4K setting or an incompatability?
Example Screenshot:

That would indicate that it is a single layer DolbyVision encode that doesn’t have a SDR layer

Right, I think I follow, so in simple terms;

  • The Vero4K doesnt have a DolbyVision Licence, so will not play this format.

  • The rip itself, does not contain dual formats, only a single HDR DolbyVision format?

Correct that is what I assume (mediainfo will tell details)

Seems to be the case, thanks very much.

Yep - single-layer Dolby Vision doesn’t have to/usually (*) use YCbCr colour-space, and instead can use ICtCp representation instead. I guess the HEVC encoding uses similar compression so you get I mapped to Y, Ct mapped to Cb and Cp mapped to Cr or similar?

(*) AIUI Some UHD Disc ripping software creates a non-standard DolbyVision single layer file from a UHD Blu-ray dual layer file by discarding any Enhancement layer data, and muxes the Dolby Vision RPU metadata alongside the HDR10 HEVC video. This IS YCbCr - but it is seen, I think, as the same as a totally minimal enhancement layer (which many - but not all - UHD Blu-rays contain anyway)?

Out of curiosity how does the licensing model work? Is it a fixed fee from the hardware manufacturer or a fee per device sold? Is it something that can be retrospectively added to devices?

I’ve had discussions with Dolby and it’s a bit complex unfortunately.
Don’t hold your breath for now.
