I hope all you counseling to suck it up don't share this opinion to the people at the Gun Shop. The reason should be obvious...
OP, in spite of the digital drivel asserting you are being unreasonable, you are not. Are the blemishes just something that can be scrubbed off? I'm assuming you've already given it a go. If so then clearly the finish is inconsistent, why? Working on the assumption that the surface treatment is important (duhh...), and its inconsistency may equal unprotected metal I think that this can only be described as a Defect. The only reasonable response from FOC would be send it back, if it is actually cosmetic give the OP the choice of having it sent back to him, or sent on to Colt Canada on the OP's dime to see if they feel it needs "repair"...full stop. Anything less is lifting that middle digit. This is a high end rifle after all, not meant for everyman, it's not unreasonable to expect a consistent surface finish, and if it's not, at the very least have the Manufacture inspect it to ensure it will do what it was designed to do, protect the underling material. Perhaps if the Distributor, or Vendor took the extra minute to do a quick inspection before they finished packing the item this would happen much less, like Ebola, I rarely get a new rifle without some annoying mark, etc. It shouldn't happen in the first place, I've spent hours watching Savage Employees pack up rifles yapping with the Shipper/Receiver (5-10 minutes at a time). The work stations the Shippers work at are well lit clean etc., cosmetic defects should be easily spotted. I expect Diemaco/CC would be the same, unfortunately the time I stood there like a dummy for an hour their security procedures meant I was restricted to an area I couldn't see nada.
In the end the just shoot it camp is probably correct though. Unless this Rifle is going to see service in a harsh environment the point is moot, I can't see how this will effect how it functions.
