You are also incorrect. It's both. For instance upon experiencing a novel, pleasurable experience, one you didn't know to anticipate, dopamine levels will increase above baseline. It will then drop below tonic levels before returning to the baseline, creating mild, even unnoticeable discomfort, driving longer term desire / motion to find / anticipation for more of the thing in the future.

Noradrenaline release necessarily causes dopamine release, but also an increase in the activity of dopamine beta-hydroxylase, which starts converting more dopamine into noradrenaline — hence the drop below baseline, discomfort and drive.
