Ok, Seth I hunted around in the AVS owner's forum. Lots of folks are applying SM offsets to get much better skin color. No more "sunburned" looking people. Green improvement, let alone black improvement, doesn't seem to be as commonly cited, if at all.
The guide that most people seem to be using, and referring to, is by someone named "mistah_g". Here is a pdf dl for the guide, at least that is what one poster had linked after some searching.

I *think I remember* someone might have said that his recommended settings are for "normal" temp, and not warm. Some people seemed to have missed that part, switched it to normal, and then were very pleased (for they were disappointed before).
Of course there is unit to unit variation, and furthermore, someone might have implied that even the default settings could vary.
mistah_g's guide isn't the only one that was cited. Lemme look some more. Can't find after a moment's try... mebbe later, I'll try again.
One interested consumer noted that CNET mentions less than ideal deinterlacing, particularly with film/24, but they did say it was hard to notice. OTOH, this consumer threw in the Spears/Munsil test and said it looked great. He also said the following:
Hey guys, I'm no calibrator or videophile but I just learned a little tidbit of info. I have a calibration disk that has an Image Cropping test. The Size 2 mode in the Advanced Picture setting passes the test, the Size 1 mode does not. I have no idea what this means in regular TV watching or if it's even discernible to most people (probably not), just passing on the info to those who care. From the user guide it says that the image cropping pattern is designed to show how much of the image encoded on the disc is visible on the screen. Size 1 didn't show all of the info on the screen, Size 2 did.
Someone educated him on saying to use Size 2. Size 1 can be used for bad looking channels with visual noise at the borders.
A different consumer said that he passed all black and white reference tests, but in order to so, he needed super white as on in the PS3. IIRC, funnily enough, this setting might have caused some issue when running through an Onkyo 805, but I can't remember what exactly. Oh, this crazy world of AV.
