I would be interested as to what you find out, so please post back it you do give it a try.
I did a little testing in the service menu CMS.
When you enter the service menu it is interesting to note that in the grayscale section, there are default offsets for each grayscale temp. Using the "reset" option does not change these values, so they seem to be hard coded. Though I wonder if vary from unit to unit. I wrote down all my defaults for each mode before hitting reset! Luckily I didn't need to re-enter them.
In the main adjust menu there a are selectors for color temp and mode. I was confused at first if this is where you could set the default temp for each mode but after testing, it does not appear to be the case.
The actual CMS is interesting as it has the following setting for each color and by default all are set to 0 for each mode.
Ang. - not sure what that is
I think those are the settings...It's been a few hours and I'll look again tonight.
There is also a pause option that freezes what is onscreen so you can adjust while it is paused. There are also before and compare buttons, but I could not toggle to them.
The only options that I found to really make a difference were the Skin and RY1 settings. I found that setting the Skin did help to get a more natural skin tone. RY1 was useful in getting rid of some red over saturation.
Again these are all very subjective observations. I have not done a proper grayscale calibration yet, as I still need to get myself a meter. So I am doing the best I can, using my ISF calibrated 60" DLP as a reference for what things "Should" look like and trying to match as best I can. My goal is to get believable color, since accuracy is not possible without a meter.
I'll play around some more tonight and report back my findings. These settings probably won't be great for getting accurate color points, but they might help in taming some minor color issues.
