Maybe a silly question but how can I check if HDR is working correctly? Or let me rephrase I suspect it's not working in my case.
Because when I check my TV settings I usually can see if a HDR source is detected. However when I uselibreelec I don't see the HDR icon on my TV. But the screen looks ok prior to this version HDR content usually looked like it had too much white in it but I can't see any of that.
When I use Kodi install via Windows I can play the same HDR content without any issues. And in this scenario my TV does detect the HDR source (because it shows a hdr icon). I also see in the kodi settings under video a toggle to turn off/on hdr which I don't see in the Libreelec version.
I tested with a NUC dual boot libreelec beta and windows 10 / kodi install.
