HDR to HDR Tonemapping Swiftfin

[gnattu]

I think it is the limitation of the vlc player and you have to use the native player for HDR playback unfortunately.

If you want to have better HDR support and don't mind use 3rd party client, you can try SenPlayer which has better HDR playback but that is more of a media player with Jellyfin support than a jellyfin client.
