I've checked with test patterns and IMHO best settings are:

Driver 16-235 -> Kodi Full -> Dithering On/Off -> TV Limited

Driver 0-255 -> Kodi Limited -> Dithering On/Off -> TV Full

With your proposition (Driver 0-255 -> Kodi Full -> Dithering On -> TV Full) i've total mess with black levels. Whole calibration pattern for black is totally black, i cannot see flashing even levels over 16.

Best one is:
Driver 16-235 -> Kodi Full -> Dithering On/Off -> TV Limited - everything in test patterns is 100% correct. I only cannot see much difference with dithering On/Off (looks the same IMHO).

In such configuration xrandr reports:

Broadcast RGB: Limited 16:235
supported: Automatic, Full, Limited 16:235

and autostart has:

xrandr -display :0 --output $OUTPUT --set "Broadcast RGB" "Limited 16:235"

For quality, none of the xrandr Limited modes are best.

In order of best quality working downwards:

#1: Driver 0-255 + Kodi Limited + Dithering On/Off + TV Limited
#2: Driver 0-255 + Kodi Full + Dithering On + TV Auto/Full
#3: Driver 16-235 + Kodi Full + Dithering On + TV Auto/Limited

And those three are the only real viable options. #1 is essentially untouched - the holy grail of video purists everywhere. #2 looks very good, but it's doing a LOT of processing to the image, which means it's what I'd use only if I'm unable to force my TV to accept Limited input on a full-range signal, as is required for #1 to work correctly. #3 is likely to be the default option in Kodi, but it's just as processed as #2 and yet still has minor visible banding, which makes it a very distant third in my book.

Now, will the average person sitting at an average distance from their TV watching typical real-world programming notice any difference between #1, #2 or #3? Probably not. But if we were average, we would not be here in this thread talking about this!
