This would indicate that it's working correctly and outputting the full range in games, right?

Just a couple other flavour questions while we're here... For starters, why do you set the Gamma to -1 on the TV? And also, on the colour tests I found that it was most accurate to set Tint and Colour to both 50/50 and 50, respectively. Am I doing it right? The goal was to set the RBG filter to each colour and ensure that the flashing colour boxes match the background as much as possible, correct?
Happy new year!
Yes, it sounds like the PS3 is outputting full range RGB.
1) RGB full range + black level "normal" =
correct
2) RGB full range + black level "low" = crush/clip
3) RGB limited range + black level "normal" = washout
4) RGB limited range + black level "low" =
correct
I set the gamma to -1 because it seems to me like the gamma is a little low (< 2.2) based on some eyeball tests.

(Note that those types of tests ^ will only work correctly if the TV is in
"PC" mode where it is NOT subsampling the picture.)
Correctly setting the gamma is more advanced calibration though and is better done with a meter than by eye.
On the Flashing Color Bars pattern, I believe all you need is a blue filter. There are a few more patterns that need R, G, and B filters but I don't think that one does.
On my set, green clips first before the other colors. I had make some adjustments to keep green from clipping to early, and that meant either lowering the white point, or lowering the overall color. I lowered the color which made the tint and color behave differently in the Flashing Color Bars pattern. Setting the color to 38 or 49 for Standard and Movie respectively kept green from clipping and the G46/R54 tint was the setting that made the bars blend the best with that slightly lower color.
However, I just did another calibration pass the other day and ended up lowering the white point slightly in order to have the colors track better. I updated my calibration post with the latest results, which now has the tint at 50/50. The color saturation is higher to compensate for the lowered white point. The Flashing Color Bars all blend together with the current setting, and on Misc A4 Color clipping pattern, the colors clip at about 235 which is where they should clip at.
When you calibrate, changing a setting in one spot affects other spots. Raising or lowering the white point will shift where the colors clip at. That's why its good to go back and check previous settings (white point, black point, color clipping, etc) to see if they have moved after you've made adjustments to other settings.
