Default Cummins 550 QSB 6.7 Turbo paint turning yellow

After running the engines pretty hard in the Emerald Coast poker run last week, I noticed my white turbo paint looks yellow, like it got way too hot. Is this cause for concern?
These engines run with 40lbs of boost at WOT, that is about double of my F250 diesel truck.
