I had this straightened..
The place I used have a 3D laser scanner with built-in sonar
(not my wheel results)
They heated it up, pressed it out bit by until it was near perfect, but sadly yeah they had to grind a little off the back to make it the best it can be, it drives like new now.
Years ago I had a wheel that was straightened by eye and DTI runout gauge.. that never felt perfect and had a tiny bit of vibration no matter how many places I had attempt to re-balance it after.
