Playing dolby vision files on non-dolby vision tv results in black video, but audio plays normally

Describe the bug

I have dolby vision files I made with MakeMKV, remuxing from blu-ray. So these should be HDR10 compatible BL+EL+RPU dolby vision video streams.

I have two TVs, one that supports dolby vision and one that does not. Both with nVidia Shield TVs running Jellyfin clients from the same Jellyfin server.

On the TV that supports dolby vision, everything is great.

On the TV that does not support dolby vision, playback is just a black screen, with the audio playing. If I force transcoding by selecting a lower bitrate, I can get video playback to work, but I would prefer if the native HDR10-compatible stream was used in this case. (And I noticed that when transcoding, it seems to lose HDR, but that may be an issue with my hardware transcode setup, and unrelated to this problem.)

On the Shields, in display settings, they properly display the capabilities of the attached TVs:
On the Sony TV that supports Dolby Vision, the shield shows Dolby Vision as enabled.
On the Samsung TV that does not support Dolby Vision, the shield shows HDR10 as enabled.

I'm trying to switch from Kodi to Jellyfin, but when some things are hit/miss in jellyfin, it's hard to get the family to use it after something doesn't work once.

This is on Jellyfin for Android TV 0.18.4 and Jellyfin server 10.10.5

If this is a duplicate of one of the other Dolby Vision threads, I apologize, but I did read through several.

I found a number of other issues about dolby vision, but most seemed the reverse of this: Playing dolby vision files on a dolby-vision compatible TV. Whereas I want to play them on a non-dolby-vision compatible TV.

#2700 is the closest other bug report I found, but I don't really want to disable specific features, I think this should be handled automatically. #4021 also looks possibly related, but 1: my TV does support HDR10+, unlike that bug report and 2: HDR10+ is supposed to be backwards compatible with HDR displays (just ignores the "+" metadata, right?)

Can confirm the issue.
Google tv streamer on DV capable tv, black screen.

My old google chromecast with google tv 4k is able to stream DV content to my tv! Tv recognises the DV signaal.

And another tv without DV support and a firetv stick also black screen

This appears to contain the server side solution, but needs implemented on client.

Yes, that looks promising. I'll subscribe and when it's out I'll re-test.
