Probably. Compared to the front rotor it seems the caliper is also slightly inclined relative to the rotor. It's difficult to see in the picture, but the part of the pad that is at front is not worn, while the part at the back contacts the rotor fully.
In any case, I suppose milling the posts will be an issue in case I need to use the warranty. I'd do it if it was an old frame, but I'm not willing to do it on a new one.
