I decided to use the Custom profile and Normal temperature.
After getting in just right (see pdf below), I decided to wrap it up exit the service menu and go back to regular tv mode.
I selected the same Custom Profile and Color Temperature and took measurements. The grayscale and gamma were completely off. I reset the profile, but had no luck. I did a master reset but no luck either.
When I went back to the service menu, my calibrated settings were there and remeasuring gave me the calibrated grayscale and gamma.
From what I can tell, the changes on the color temperature I made as well as the other settings used in the service menu are not getting carried over to the user settings. Not sure if this is an issue or just me being a noob; in any case, I hope I get some help from the guys that recently calibrated their units.
I am including a couple of pdfs: the same profiles and color temperatures: one from the service menu and the other from the user settings.
I have noticed this on my 50PZ80U also. When in the service menu be sure to select the mode and color temperature setting. 9 changes the mode, 7 changes the color temp.
The only way I've managed to set the gray scale is to make a change to the cuts or drives, exit the service menu, and measure again. Somehow this seems wrong, but measuring while in the service menu does not have the same effect as measuring outside the service menu.
I have not tried resetting the video from the user menu.
There is a "method" setting, from 00 to 03, 03 being the default, but I have no idea what it does.
I have also noticed the black levels on this set have increased quite dramatically since new, 0.027 new to 0.063 at 1100 hours.
