I have an LG OLED CX, and the native Jellyfin client supports DV without any issues. The only downside is that the TV itself has to be connected to the network, which LG is actively working on making less desirable

This is in the hardware section of the Kodi forums. Massive thread near the top. Some technical discussion on pages 225-250 about this matter.

Devices include Vero V, Ugoos, Homatics. (Apple TV is indeed an option as well)

Check the spreadsheet linked on the first page.

I will mention DV is a premium experience and you’re not going to pay less than Apple TV prices for a box that can do it. $150 really isn’t much.

There is DV -> tone-mapped to HDR output stuff but it’s not true DV. That you can do on a Linux mini-pc and so on.

CoreELEC can do it on Dolby Vision certified devices if you're looking for a open source solution.

If you don't want to get a new device, you can try Android TV on x86 with the official Jellyfin app. I have no idea if it'll work, but it's worth a shot. https://github.com/LineageOS-TV-x86

Jellyfin on an Android TV does DV just fine here, so any android box that supports DV should work I guess.

I don’t know about Jellyfin, but Stremio supports Dolby Vision (iirc). I assume you have a debrid service, with Stremio it’s basically plug and play

edit: Stremio should be inside LG’s OS

Does anyone have a working setup

Any Jellyfin setup would do, as long as whatever you're watching it on supports DV.

I agree Apple TV with Infuse is a bit expensive, but it’s worth it for the seamless experience imo. The quality of the Apple TV hardware means you’ll never have to deal with transcoding, and the local caching is spectacular. If the Infuse subscription is what’s stopping you, there are other cheaper and free apps for the Apple TV that support DV via Jellyfin (Swiftfin and MrMC are pretty solid) but the Infuse interface is hard to beat.

I use jellyfin with the shield tv (tube version) w/ an lg g1 oled. No compatibility issues for all my high bitrate, dolby vision, dolby 7.1 files. However, performance of this old device is starting to get bad. Requires an occasional reset.

Another reason I can't justify leaving Plex 😭
