From the OP's album:

The inside has a similar profile to the outside.
So, it is quite possible that the issue could be on either side of the hub and locknut or the skewer. (emphasis added)
As I mentioned, sitting the fork on the hub without the skewer will give a better view of how well the axle is seating in the notch..

Of course, we don't know that it's the back end of the axle, but can reasonably surmise that as a possibility worth serious exploration.

Spent all morning again trying to figure out what’s going on. Here is another pattern discovered today.
On both front wheels(OEM Fulcrum that came with a Canyon and Aftermarket). Both are symmetrical rims.
When I position the wheel in one orientation, it’s dead Center and when I flip the wheel in the other orientation, it’s off to one side. It’s happening to both wheels and it’s always off to the same side.
So this tells me the dish is not 100% as well but normally when dish is a factor, it would offset to the opposite side off-center when flipped. The fact that it returns to center on one orientation tells me that the fork alignment is at play here and the true center of the fork is off.
let me know what you think..

Just don't try to bend anything. By the way, taking a file to it would be the quickest way I know to void the warranty or make the frame unreturnable.

At this point… I think I give up… it shouldn’t have to be so hard to get a wheel center vertically.
Regarding inner side contact, playing with the fork again just now, without the skewer and without the axle locknuts even touching the inner blade, I can see the wheel slightly tilted/slanted vertically. If I Center the wheel manually by hand, I can clearly see/feel one side of the dropouts leave the wheel axle and not touching anymore. At this point, this is the only way I can get the wheel to center properly which basically means one dropout is held by the force of the QR nut instead of it sitting in the dropout.
after two trips to my local bike shop and hours of trying different skewers and wheels… I will just wait for the 3rd fork.
I sent few photos to my friend who also owns carbon bikes from other brand and he said the moulding looks like crap as well. His bikes look almost perfect in that dropout area. I know the moulding tolerance is just cosmetic but cosmetic issue like that is an indicative of quality which there is no guarantee that the dropouts are going to be perfectly aligned.
