What changes from sea level to 30kft is the pitch angle (and yes AoA angle)

You start of climbing at a steep angle at lower altitudes and end up climbing at a very shallow angle at higher altitudes.

Thus pilots were very use to the idea of changing the climb angel as they climbed

I agree there, but this isn't an extended climb to 30kft, its an extended climb to 10,000ft from 1500 ft. In the context of this test the climb angle doesn't change much.
