Looks fantastic!!! You must be very happy with the picture.
Oh, and GREAT write up on the gamma/calibration process in post #144! Thanks!
The only thing I would check is your brightness setting. Might try to bump it down one notch and see if you clip blacks with the near black patterns. That may also be why the gamma goes so low at 10%. It looks like you may have room to bump it down one notch and not clip blacks, which would also improve your gamma slightly at 10% (might bring it up closer to 2.15 or 2.2). I could be wrong though.
