Nope. I personally have two HDR devices and two non-HDR ones. I don't want to keep two separate copies as this takes up more storage, requires me to get two different versions whcih means the progress won't be synced ebtweent the two, the subtitles may not be exactly the same either, etc.

I want to have one and only file that will optimally on my main device (HDR) but which also work reasonably well on a secondary non-HDR device.

Ideally Jellyfin would handle the latter two points (and I think it does), but the first two are good reasons.
