I would say that is a safe assumption as the plates are all electronically controlled, so the contact points are better managed than on a manual box, as a manual box is more designed to allow for crap human control. (let's be honest we have all hit a gear - or not when we have been driving with a bit of spirit)
As hurdy pointed out though, there is always going to be a limit to the tolerance it will carry before beginning to fail, like all things.
