SOLVED: Direct Play 4K HDR Issues

[Daniel Brown]

I am trying to make the switch over from plex as i love the idea of jellyfin! Most of the things seem to work okay, however, 4k content (HDR in particular) doesn't direct play and transcodes when plex does not (it direct plays). This also effects the HDR as it is washed out due to it not displaying in HDR.

If it matters, i'm running these both on unraid.

The video file in question has the following details.
