There's no reason why a Working Space gamma and a display gamma have to
match or even be close. There are slight advantages to a 2.2 gamma in a
Working Space.
I don't calibrate my Artisan to 1.8 or 2.2 (I'm on a Mac). I have it set to
it's own, unique native gamma (there's a way to do this on the Artisan). The
artisan can the set to the natural TRC and records it to the ICC profile -
leaving the DAC LUT linear.
Outside an ICC savvy application there might be reasons why you'd want a 2.2
gamma and a 2.2 Working Space but in such a situation, the preview is such
that anything is possible (your mileage may vary).

I'm talking about an untagged file or a file outside of a color managed
application. Assuming the person wasn't intelligent to place a tag in the
file, we have to simply guess. I'd start this guessing game picking
something like ColorMatch if I knew the user was on a Mac but if that didn't
appear correct, I'd try sRGB. After exhausting all possible "common" Working
Spaces, if the file still looks ugly you really do have RGB mystery meat.

I really hope that's not the case!
