Did some testing on my setup. I have:
OpenElec latest Fritsch build running on the Asus Chromebox
Denon 4520 AVR
JVC 4810
I first tried to just remove all the xrandr settings I had in the openelec setup and unwind any settings I had in kodi.
This meant - chromebox would be at Limited ( I think?) and the projector was set at standard (16-235). I also turned off the use limited range I had set in kodi.
I had dithering setting was enabled by default.
This looked pretty good but the grayscale ramp still didn't look 100% smooth like it does with the full/software limited range option I had earlier.
I think set xrandr to full and set the projector to enhanced (0-235) with dithering off. This looked good but had some banding. Turning on dithering here gave the smoothed grayscale as it looked perfect.
I am guessing this isn't exactly what I should be doing though. I thought the unwinding of all settings should give me the proper input.
Thoughts? I am a bit new to all this color space stuff....

If your beamer is full range:
Set xrandr to full range, disable kodi's Limited Range setting, turn on dithering with 8 bits.
If your beamer is limited range:
Set xrander to full(!) range, enable kodi's Limited Range setting, turn off dithering (while it does not harm).

Which features are you thinking of in focus of video decoding and rendering?

A quick question, as I got lost with the lots of new info.
Is Braswell working and supporting the following:
- non-4K content encoded with HEVC h.265 (1080p, 720p)? The hardware should be capable as per the specs. H.265/HEVC @ level 5 (GPU accelerated)
- is n3150 capable of Hi10P encoding without any problems?
Thanks!

if the beamer can run at full range, then use this.
Backend: Asrock N3150 with Ubuntu 22.04 Server with TvHeadend
Living Room: Nvidia Shield with Kodi

Yes.
(leaving out the NV12 to RGB conversion for now) :-)

okay so I am a little confused.
I have always been using this:
- Full range xrandr, limited kodi + limited projector
I guess I thought I was going to be able to get rid of the limited kodi as the washed out blacks in Kodi are a bit annoying but no biggie.
Since I have always been doing this - should I really see a change? I assume there is nothing really different?
I could run full on the projector but I would have to switch for other sources so doesn't seem ideal.
Thanks!

Don't let us drift into religion ... just use some test samples and see if color range is as expected. ...
And again: this color discussion is only valid with our here given EGL build. All other kodi + vaapi does not work that way ...
