I also have a 2014 Summit but in Cashmere and was in the same boat as you trying to decide whether it was worth the effort and costs
In the end I removed all the badges (except the one molded into the rear tailgate) and vinyl wrapped all the chrome (Black around the windows and a silver on the lower trims), colour coded door handles and had the lower skirts painted.
Personally, I love the way it now looks and am really happy.
I think with the darker Granite it would look even better.
End of the day, it is your ride and your personal choice
