Hi! Tried to read all posts before replying but there seems to be quit a lot of different problems going on and not only for the LG OLED65C8. It looks as though there is a fix coming which is great. I just wanted to confirm that applying the hotfix as stated in Video improvement details - #7 by obstler42 does work fine for me on my LG OLED65C8 with the HDMI ULTRA HD Deep Colour setting on in the TV. Kodi is set to 1080p in the gui and autoswitches to 4K HDR. I am not sure what it is that I am missing by running the hotfix? Lesser picture quality without me knowing? Anyways, hope this helps others on the same TV and do let me know if you need specific testing with this TV.
