It's just the lower "grille" that has a chrome accent, right? The upper grille looks exactly the same on the 06 I saw. The lower "grille" is an integral part of the plastic bumper cover. However, I wonder if that chrome accent isn't just applied after paint.
I went to Home Depot today (BTW, a 10 foot 2x4 fits perfectly inside the cabin from corner to corner) and parked nose to nose with an '06 (also platinum, almost like looking in a mirror). Got a nice close-up look at that new grill. Very nice. I probably wouldn't have even replaced it like I did my '05 grill.
Not only are there more "teeth" and it's a slightly tinted chrome, but the shape of those teeth are different as well. A little sharper cut inward, not so bubbly.
