Kinda hard to tell just from pictures. Especially with sun faded paint, but my guess is there’s a fair chance it’s been repainted. Wrapping the paint into the door jambs is the proper way to paint and not a lot of shops go to that level.
What is the paint code on the door sticker? Should be a 2 digit code for exterior paint. Or just take a picture of the sticker. If the sticker is painted over, it’s definitely been a repaint on at least the door. If the sticker is missing it could be a repaint or the sticker peeled off, in which case to find the original paint code you would have to get a Marti report on the VIN or something.
Usually indicators of paint are things like poor orange peel (too much or not enough), tape lines on panel edges, jambs not painted properly, sand scratches in the paint (poorly done body work), mis-matched shades between panels (only if the whole thing hasn’t been done at once), paint code not matching the general color, runs, dirt in the paint, fish eyes in the paint, and overspray on things. Of course this all gets complicated, my dad has a ‘79 that has all factory paint (he bought it brand new and owned it the whole time) and for factory paint, it looks like it was painted in a driveway on a windy day.
