Zoyd, have you tested the "Near Black" patterns on the ColorHCFR section of the AVS Rec709 disc to verify that there is no black crush of the 1%, 2%, 3%, 4% windows with these tweaks?
I too have a 51" D8000 and before I take it off the wall, attach the stand, move my BR player, not to mention get plastic screw drivers and open up the TV in the middle of the night, I want to have a plan. I don't want to go through all this more than once.
My black screen measurement with D3 Pro (calibrated) probe was 0.014 with CS off and 0.020 with CS on. Not much different from yours. As you know, the D3 probes are supposed to be quite accurate at the low end measurements, more than even the i1Pro. I got mine through ChromaPure and the calibration of the probe is automatically loaded into CP. They sent the correction matrix, so I could use it with any other software by loading the corrections manually. I'm just spending the time getting to know at least this one product better, but eventually would like to verify it with another one. What software do you use?
My plan is to measure at all the test points to make sure my voltages are to specifications as shown inside the panel, adjust to spec if any are off, and then just to the Yrr tweak.
I'll follow your instructions to find the Yrr induced artifacts and then probably back off a little more than the minimum required to make them go away.
You went from 0.16 to ~0.06. This is already the darkest and most uniform TV I have ever owned and will be happy with any significant improvement and especially anything below 0.10 ... unless I get greedy ... which is something I have been known to do. heh
