I would suggest using the Kodi Dolby Vision builds for this, since it's patched to skip the HDR10+ when Dolby Vision is also present.

Otherwise, you can try this script: https://gist.github.com/quietvoid/175d7d16248848e2fb299f9eb1bd2c38
Which is based on yusesope's script, so it requires python ...

Hello! Sorry if this is a dumb question. I have an mkv file with both DV and HDR10+. This triggers dolby vision on firestick, but only shows a black screen. How do I solve this? Should I remove the HDR10+ metadata? And if so, how?

Thanks!
