Apples and oranges.
A calibration can be delivered as a physical chip or flashed into an ECU via some method (eg OBD diag port). The calibration used, in either scenario, can be either an off-the-shelf cal or a custom mapped item. The latter can be done either offline or online ('live mapping').
I think it's good that people understand these terms properly.
