After the loudspeaker levels are calibrated I usually leave levels as is, but sometimes in films the center channel, surrounds, or sub level can be a bit too loud or soft, so I make small adjustments on the fly. I have the on-screen display shut off so others in the room are not aware of or distracted by my level changes. (Our Yamaha AVR has direct access to channel levels and I can read the AVR's front-panel readouts from my seat.) Conveniently, the temporary adjustments are erased when the AVR is shut off.
In short, I suggest calibrating first, then tweak as needed.
