Unfortunately there are too many high range brand new models from any brand with similar and even higher price than the new R3, with more visible marks on the manifold and that the manufacturer would consider as normal.
I'd refer as an example to the brand new BMW 1250RT that I have tested and whose manifold turned brown and purple from the first miles (when I tested it, it had only 3000 miles)...In comparison the 2 small spots on the R3' look to me really minor... :
