Low power encoding for H264 is supported, but not HEVC low power encoding. Low power encoding is OPTIONAL for Coffee Lake.
Tone mapping on the server is supported. It does require that you install Intel's OpenCL package, if you have not done so already.

Without being on your client system, it is hard to say what is going on. The ffmpeg log you shared is downmixing the audio from 7.1 to 5.1 while sending the 4K video unmodified.
Do you have issues across the board with 4K content? Or just this particular movie? If it is just this particular movie, the problem could be a malformed container.
Thanks a lot for the settings help, especially with the low power encoding!!
The issue WAS not only with 4k and not only with this one movie. I changed a new setting for my proxmox VM on the client and it seems to have fixed everything!
I activated vIOMMU=Intel in the machine settings and now everything except for HEVC runs butter smooth in direct play. Setting "always transcode HEVC" in the linux player fixed that too. Since CPU load stays pretty low now I was right in my initial assumption that the CPU might be old but good enough! Direct play for h264 and transcoded HEVC works well.
There is only one last thing I would like to ask:
Since I want to use the jellyfin linux player in some sort of kiosk mode (always exclusive kiosk mode) I would like to disable/remove the "exit full screen" button in the lower right corner of the playback controls. Is there a way to achieve this?
