meaning - "It took a year until she got/had got/had gotten over it"

I am trying to figure out the correct use of perfect (past perfect) tenses:

• It took a year until she got over it.


• It took a year until she had got/gotten over it.

Are both correct?

If so, I think the latter means that it took a year until it was all gone and she was fine again (I mean that event is closed already), while the former is more "immediate"?
