I also thought by 80% you meant my 75%W measurement which to my understanding is not that different from 80%. Calibration for black level for my HTPC I think does actually improve greyscale versus a meter that does not, but that's probably not very relevant, and again this is from my limited knowledge on the subject. Do these results look appropriate for a high power screen? I expected really to get gamut dialed in, then hope for the best with greyscale using the automatic feature on the HTPC.
By 11-step grayscale, I mean that you measure at 11 different points (0%, 10%, 20%, etc.). You have to tell CalMAN that you want to use that many points. Also, the layout you're using calls for 2 different sets of measurements: 1 set for grayscale (at 30% and 80%), and a separate set for gamut (that's your 75% W,R,G,B,C,M,Y and 100% White).
I believe you have it a little turned around, Steve. A properly used and accurate meter will
help you improve grayscale and gamma as much as the display's controls will allow. Calibrating black level (and contrast) is a first step and by itself does not necessarily improve your grayscale.
The closer you can get your display to D65 and a good gamma curve, the easier it will be for your HTPC to build an accurate profile.
