That is a very nice truck.
I have seen nothing published by GM in any manual that specifies if/when the tailgate letters started to be painted (or the color). Nor has anyone ever posted the official "GM" answer to your question. In this type situation, I'd let the Stovebolt consensus you read be the official word. Especially if it's the thread Denny, Tim, & longbox (Bill) were posting in (c 2007).
My 55.2 tailgate lettering is not getting painted.
