That doesn't look so bad to me; it seems closer on the fork of my rando bike and I don't have any rub even when out of the saddle (steel fork and QR axles too)
I can get the caliper mounted with a tiny amount of rub on the rotor (not consistent though, indicating the rotor is slightly out of true from new). There's no rub on the fork leg though yet...

Try it first, maybe it's not a problem?
