Download a photo of a new Shimano outer chainring from some seller's site. You'll see that it looks nearly identical to yours. Yout chaintings do some some wear, but IMO it's well less than 10% of the usable life.

We routinely get the same questions from people who look too closely at their brand new bike's chainrings. (search "is my new chainring defective" (or similar). Mount the rings, oil your chain and see if you can put some reasonable wear onto these almost new rings.
