Dolby Vision on LG G3

[Paradox]

Hello, what would be the best and cheapest stick or streamer to get Dolby Vision on my TV? I'm currently streaming from my PC to the Jellyfin App in LG OS. I swear it used to play all DV files before no problem, but an update made it unable to play profile 7 DV files, which are most of my DV movies. It can still play DV 8, but everything else it defaults to HDR 10. 

I was thinking about getting an Nvidia Shield because I've heard it's the best streaming box, but I don't use any other apps besides YT, Twitch and Jellyfin. If it wasn't for DV files, I'd just keep using my TV OS tbh. That's why I don't want to overspend.

Edit: I updated the OS yesterday and now I can't play any DV files. Fuck LG I guess.

Can you share your jellyfin logs via pastebin? And provide server specs and OS.
