Your description of the video chain is excellent, and I suspect that the problem I am seeing is due to incorrect setup for my display (maybe my display on "auto" is not behaving correctly) or my AVR.
Perhaps with the test patterns I can figure it out.
It's been a while since I looked into this, but I think if you're trying to get untouched limited range output, you'll need to either disable VAAPI or use swfilter. The VAAPI driver uses hardcoded coefficients for YCbCr->RGB transform which scale from 16-235 to 0-255 levels. swfilter gets around this limitation by grabbing the original frames.
