I have issues with Kodi since forever, some movies are just showing purple/green colors.
And it is pissing me off since forever as I need to get a different encode.
I think I have found why.
My TV (Samsung Q90T) doesnt support Dolby Vision, which I am aware of and I am avoiding such movies.
My setup:
RPI5 ----> Denon x1700h ----> Samsung Q90T
Now, even if TV doesnt support Dolby Vision, AVR does support it.
What the problem is, that some "copyright holders" are releasing movies with both Dolby Vision and HDR embedded.
And in this scenario, probably Kodi, sends Dolby Vision data instead of HDR.
I was looking for an option to prevent AVR from advertising it is DV capable, but havent found any.
Is there any option to force Kodi to send HDR data instead of DV?
(I have confirmed this on two movies i had issue with. In both cases they were distributed as non DV release but had DV data attached)

Probably Kodi within libreelec wasnt build with setting to allow disabling of Dolby Vision.
