I would like to request that Plex identifies and tags Dolby Vision files with its own tag, currently a 4K HDR file will show a 4K HDR tag, a 4K file will show a 4K tag and a Dolby Vision file will show just a 4K flag.
I would like to propose flag “DV” or “Dolby Vision” - I know not many people will need this currently but its possible more people will have this content in the future.
