At least in Simple setup mode they had the sense to call it "traditional" rather than "standard".

In your final parentheses you seem to be implying that at some time during the last two years (after I bought my Mac) OS X started shipping with a default display profile specifying a target gamma of 2.2, instead of the 1.8 that mine had out of the box.

I wouldn't bet on it, but I rather suspect that they are still shipping with 1.8. I'm going away to check...
