As someone who is currently actively discerning this vocation, I can tell you it’s not the same. Consecrated virgins are consecrated. It’s different than vows.
I was reading about this in something one of the Church Fathers wrote about. Non-voluntary sexual relations such as rape and incest don’t change, because there is no sin and the person is still a virgin, as it wasn’t voluntary. St. Augustine wrote about this in The City of God.
As for the other, she would no longer be a virgin, but she would still be a consecrated person. In the past, if a consecrated virgin lapsed and lost her virginity, she could still receive the sacrament of Confession, but she was barred from receiving the Blessed Sacrament, with the exception of as viaticum.
It’s for reasons such as this that it is expected that someone has lived a number of years under a vow of perpetual virginity before requesting the consecration. Vows undone. Consecrations can’t, so if there is any question as to whether or not one can live a life of perpetual virginity, the person is not to be consecrated.
