DV files do not play on my OLED48A2PSA

[rohankrishna]

So recently I heard that jellyfin from version 10.9 onwards will be able to remux DV files from mkv to mp4 or .ts container to trigger DV playback so i upgraded my server to jellyfin 10.9.6 but still it does not trigger DV in mkv and plays the fallback layer(HDR).All the files I have tested are DV profile 8.1 which contains fallback HDR layer.I also noticed even if I enable the "always prefer to play in fmp4" option in playback both on server and client...it somehow transcodes the files.

My setup
Jellyfin server 10.9.6
Windows installation
Client LG OLED48A2PSA
Jellyfin webos app
