I would contact DL later and see what they will do as the flight leader will document the problem and then DL can verify it.
Also, if there was a nonrev in D1, the purser should have told the nonrev to switch seats with you, ideally asking you first whether you would like to switch seats. The same should happen if the AVOD system at your seat isn't working and cannot be fixed during the flight.
