Dolby Vision on LG OLED

[pxr5]

Both Dolby Vision and HDR10 mkvs both work fine on a Fire TV Stick 4K Max. The problem arises with hybrid DV/HDR where the Firestick will present with a black screen. Kodi has solved this with a setting to force either DV or HDR from the stream. I have it set to DV and not had any issues with the latest Kodi. I'm not sure about how the Fire TV 4K (non max) handles DV though.
