Well Bottom line I can't get the wheel centered no matter what. Its a solid 1-2mm to the left. Hold on while i get a good pic.
what you wrote below suggested you centered the wheel according to the brake, not according to the frame. remove the brake pads, forget how centered the wheel is in the brake, and adjust the screws to see if you can center your wheel relative to the frame
it may very well be an issue with your frame, and in which case, i'm very sorry to hear that you'd be exchanging things for the third time, but it may just be something else.
btw, do you have any other wide wheels? the last thing i just remembered is that when converting a 10-speed to an 11-speed, the dishing would need to be adjusted, so it may very well be just that; alternatively, do you have another 11-speed wheel on which you are running 10-speed?

how wide the super 9 is. I just got back from the bike shop and they said my Super 9 was perfectly straight and center, which now leaves me with the frame being crooked as the only possible diagnosis. I've done EVERYTHING possible to make it work, but all has failed.

very helpful to getting wheel centered in between the brake arms, but thats it. Wheel just doesn't sit flush with the frame. I can take a picture if you'd like?

The brake arms are secondary. Brakes can be centred to the wheel after they wheel is centred to the frame. If you are centred to the brake arms but not the frame then it might well be the brake that is the issue.
I may have missed something or misunderstood, whack a picture up.

If you have a wide wheel and are using 7800 brakes, chances are it's the brake.
While you can adjust how wide the brakes will open, the is accomplished by moving one brake arm only while the other stays fixed. So if you are trying to center your wheel according to a brake at its widest position, things will be off. I had to resort to sand paper (only on one side) in order to get the proper brake clearance and having the wheel centered.
