No, it's scaled but linearly and not redistributed.
There's still studies of relatively raw distributions and it still looks normal. The biggest deviations from normality are due to an excess mass in the lower range due to disease, and a tendency for scores to spike a tiny bit at certain numbers, probably due to people administering the test fudging a bit sometimes for various reasons.
