Just tested your video on 4 different players: Fire TV 4K Stick, Vero 4K+, nVidia Shield TV, and Odroid N2. All played the clip smoothly, w/o stutters (all my players are wired, playing over SMB or mounted shares), but only the Odroid N2 got my projector to engage HLG HDR mode. Colors looked great, while washed out as expected on the other players. I also have a couple of VP9 Profile 2 HLG videos and none of the players enable HLG HDR mode for them. Looks like only HEVC HLG works w/N2, not VP9.

I'm surprised why Fire TV 4K Stick won't engage HLG HDR mode w/local files via Kodi as both Smart YouTube TV and the new official YT app do.

BTW, what drone/camera combo do you have? Nice 4K PQ.

Thank you for testing. I also surprised that Fire TV stick didn‘t recognize HLG.
Quite bad news because I ordered it today specifically because of HLG HDR support.

P.S the video was recorded by drone: DJI Mavic Pro 2.

It did for me on my lg tv both with Kodi and emby so check your tv settings. Good luck
