losing privilege rather than gaining magical disability grace

I hope that's how it would be shown - although it's hard to say. If they intentionally showed all the ways in which Charles was blinded by his privileged position - and since they were numerous, I do have some hope - then I would expect it to be somewhat addressed if there is a sequel. Or if there isn't, maybe in the extras/commentary for the DVD - certainly McAvoy has alluded to it slightly, in between describing the movie as a love story between Charles and Erik.

Of course, characters suddenly gaining grace without the journey is something Hollywood does all the time...
