I know it goes without saying, but before you ride your bike away from the dealer again, make real sure that all the oil has being removed from your tyres . With any still on them it would be a real shame to slid it down the road.
A good riding friend of mine had a similar thing happen to his Africa Twin, he hit something underneath, on the slab, ( no reinforced plate on his ) but he hardly felt it, anyway before the oil light had come on, unbeknown to him, it had leaked on to his rear tyre, we came to a RH bend, he lent it over & down he went. Oil was everywhere, properly just the same as like yours was on your posted picture.
Enjoy your new toy, & ride safe , eh.
