I have no explanation for your problem.So when you switch with xrandr let's say to limited, to full and back to limited while a video is playing, you see a change in the video brightness? Because I don't. Earlier you stated that vaapi is not aware of X and directly writing out the video, and that actually sounds like "xrandr" might not affect this stream. Or am I getting it wrong?

Make sure Prefer VAAPI Render Method is enabled.That's exactly what I set it to, after making some test last night. Brightness is now again set back to 0, but I am missing tiny bits, like black 17 and 18. Looks good so far, but could look a little better..
I will have to extract the gray ramp from the testvideo as a picture, so maybe I can compare the levels and at least figure out, what level the videos are being played out. Hopefully that will work.
What I want to achieve is to be able to measure under X using displaycal ant to use the created 3Dlut in kodi afterwords. Ideally I should be able to control the output level of the grafics card when playing back a video.
