No, profiling doesn't move the target. It tries to describe what a device
is doing, period. If you calibrate first, then it describes that calibrated
state, if you don't, it describes the uncalibrated state.
And yes, profiling is all that is necessary to use its ICC description in a
workflow, but calibration is utterly crucial in that that's how you try to
get a device to behave consistently and stably. You can use profiles to
adjust values for consistent results as well of course, but the distinction
allows the possibility for people to calibrate devices without ever making
or using an ICC profile of it, which they do all the time.
