Is the Limited color range setting working correctly? When I enable it, the GUI gets darker but video content near black gets brighter. Shouldn't also the GUI get brighter with limited range? There is a big difference between picture and GUI brightness with video brightness/contrast at their default values.

 Depends on many things: hw decoder, Xorg color setting and so on ...    

Is it possible to use xorg.conf to enable limited range with Intel graphics? I found messages that indicate it's not available for Intel.

I tried command line with xrand and it worked, now GUI is at the correct brightness (I hope...). I just haven't got it to work inside autostart.sh, not sure why it's not working.

But now I'm confused why I need to use xrand to get the correct brightness. Why there is no LibreELEC GUI setting for it? Kodi's setting effect only Kodi's part, not the underlying Xorg parts? Or am I missing something?
