I had terrible performance issues on the JF app, manifesting itself similar to what you describe, until I deselected everything under the terms agreements and only kept the required terms. Turns out selecting all of that stuff makes your TV eat through a lot of memory and is specially noticeable during 4K HDR Playback in which audio is being transcoded or if you are using complex ASS subtitles, at least that was my experience.
You may also want to unplug the TV for around 5 mins to clear out some memory just in case.
Nope, the bare minimum to get Jellyfin installed. Most of that stuff is blocked on my network anywho.
On the encoding front, I tried encoding using av1_qsv and the DV metadata still appears in the video stream:
Code:
Stream #0:0: Video: av1, 1 reference frame (AV01 / 0x31305641), qsv(tv, bt2020nc/bt2020/smpte2084, progressive, topleft), 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 23.98 fps, 1k tbn (default)

Side data:
DOVI configuration record: version: 1.0, profile: 7, level: 6, rpu flag: 1, el flag: 1, bl flag: 1, compatibility id: 6While in my experience, this can be mostly harmless, WebOS seems to sometimes interpret it as actual metadata -- or there are other issues beyond my current understanding -- and it completely blows out the picture to bright magenta. Am I doing something incorrectly to strip this out automatically? Even if the metadata is persistent, how would I even verify whether the media has the DV layer intact?

What is "jffmpeg" aliased to? Is it attached to something other than jellyfin-ffmpeg 7.0.2-5?
My understanding is simply using av1_qsv with DV 7.6 and 8 will automatically strip the DV RPU and EL.
Code:
Stream #0:0(eng): Video: av1 (libdav1d) (Main), yuv420p10le(tv, bt2020nc/bt2020/smpte2084, progressive), 3840x1600, SAR 1:1 DAR 12:5, 23.98 fps, 23.98 tbr, 1k tbn

Don't use any of your filters and scaling and see what happens. If that does work, this would probably be something that needs to be fixed.

Code:
alias jffmpeg="/usr/lib/jellyfin-ffmpeg/ffmpeg -y -hide_banner -v verbose -stats"I'll give it a shot without filters today.

Again, it is not related to DV, it is webOS HLS player in general. There is no easy fix unless you pre-transcode your file and let the webOS direct play it.
