Looks like it'd sharpen out with little effort, and it's a blem so unless you're some odd collector of Kershaw Blems, I'm guessing you were going to be using so if it were me, I'd use it and assume I would have done something similar eventually. To me, it's one less thing I have to worry about since the hardest part for me when getting a new knife is putting the first mark on it. After it gets its first mark then I am a lot less reluctant about using it. Enjoy your knife and use it, that's what it was made for!
