From what I've seen on other threads, the door panels are molded from clear plastic and then painted from the backside. There was likely a thin strip of an area masked off prior to painting that might have 'leaked' a little paint through, causing your door ABL to get dimmer in those areas.

Before taking it to the dealer, if it were MY car, I would look at the possibility of taking the panel off and using some solvent to wipe away any paint that might be in the area that should be clear. I think the dealer would do the same thing, but doing it yourself wouldn't require you turning over your beloved to the service department. My 2 cents...
