I believe in XLT Sport, regardless of color of truck, the grill is the Ford charcoal color.
In Lariat Sport, the grill is painted the same color as the truck.
The Lariat Sport is the easiest "trim level" to spot from a distance. And it's actually fairly rare, compared to all the other trims and options. Yet it has been my favorite looking oem front end treatment yet.
I do believe that the XLT Sport grill is inexpensive and very paintable.
