Depends on the state. I'm on one of the states in the "Restoration by Governor's Action or Court Action" category, and I can tell you thought it is possible, voting rates are rarely, if ever reinstated in my state.
A couple of States even allow inmates to vote while incarcerated. In my now-home State, inmates are encouraged to vote and sometimes politicians will even go campaign inside the prison. That's pretty rare, but has happened.
So, it's a temporary loss in most cases. Notably, Maine allows inmates to vote and Maine is overwhelmingly white. Vermont is the same way. In my quest for more information, I found some commentary about that aspect.
