It is especially noticeable when you come to a stop as there is no airflow to dissipate the heat from the rotors.
If both sides are braking equally I would think the heat gain would be similar from passenger side to drivers side. OP is reading higher temp on one side only.
Brakes have been checked and given thumbs up. OP says problem more apparent on hills.
Maybe there are more curves on hills? Maybe worn bearing heating up from side thrust on curves?
I would swap TPMS sensors on the "hot" duels to check TPMS sensor, then have the bearing checked on the hot side.
