I'll throw my hat in:
My car came with the iconic glow grille, but I wanted the gloss black.
I got the gloss black from my local dealer, and fitted it but then felt it was all a little monochromatic up front, so I took the gloss black surround and fitted it onto the iconic glow slats. I also covered over the small slivers that are on the active shutters in black so only the slats of the grille stand out.
Bonus - The glowing function still works as that is built into the slats and not connected to the surround. I may have the first gloss black surround Iconic glow.
