Recommended OS for Jellyfin client

There's really no good alternative unless you don't particularly care about HDR passthrough, as HDR isn't much of a thing under Linux yet. You'd have to run KDE which has a subpar implementation or use gamescope which is geared towards gaming more than anything.

Not to mention that with Libelec/Kodi you're already compromising by not having HDR to SDR conversion (through something like tonemapping for instance) in the first place. Also, no Dolby Vision support, since it only works for Kodi under Android and with a device that is licensed for it; otherwise it can't decode it.

I'll begin by saying that i'm not knowledgeable enough about tonemapping and HDR in general.
Still, i hardly use that 4k monitor in my living room and i just wanted to set it up to work for guests those rare times where i need it, so even if i lose quality, at least it needs to work and have a decent UX.
