I would clean up that area and then as you continue to ride the bike, monitor that area to see if you can identify the source of the leak. Taking photos as you did is good, which you can then use as proof of the issue when you take in to the dealer.
I know it's hard to tell, but there is some fluid up at the very top left corner of the first photo. I feel like that rules out chain lube, even though it was recently lubricated. Cleaned the area off and will ride on it a little more. Likely pop into the dealership tomorrow.
