I would try using one of the headlight lens polishing products found at local auto parts store, or even Mothers chrome / aluminum polish, which is essentially a very fine polishing abrasive. It may smooth out the color differences. The grilles are just ABS black plastic. You could also just scotchbrite and paint flat black.

I've polished many a headlamp housing lens to nearly original clarity (using Wolfgang and 3M products) but there's no way I'd even attempt it on such a complicated piece as the grille.
What I would really like to know is which finish is original: the somewhat glossy deep black or the dark matte grey.
ABS plastic from the mold is similar to the "somewhat glossy deep black" but it also looks like cheesy cheap plastic. The factory originals [may] have been treated (chemically aged) to make reduce the gloss.
Was your car ever repainted? Looks a little like overspray to me! Just as a test, if this film is on the very top of the grille that is hidden when installed, try some type of acetone in one area to see if it comes off. Be very careful though, not to cause further damage. Usually finish was always semi or matte finish.

Yes the front bumper was repainted (base + clear) before my ownership.
Hmmm,this last summer I painted my 78's grille's and the frt/rr bumperettes,came out like factory in color,shade and texture. I used SEM #39143"trim black",sorta in-between flat and semi-flat. When the weather clears,I'm gonna do the inr fender wells also.Hdal
I was shocked at how well the dishwasher worked as I'd cleaned them very carefully before. Sorry for no close-up photos as they're now installed. The result was that the glossier places went away and now everything is a uniform matte that I believe is close to the original.
