Actually, no.

Note I said 28c tires - not 28mm. 28c Continental GP4000IIs measure 30mm...Schwalbe Pro Ones measure 31.7mm.

I originally bought the direct-mount caliper of the Domane SLR. I needed to use the barrel adjusters to get anywhere close to clearing the tire through the caliper for quick wheel removal (note my original comment re: wheel removal). It was on this basis that I switched out to a disc version. I transport my bike regularly with the wheels removed. Discs free me up from all of the hassle of clearance issues.
