No it’s not.
The whole crux of the issue is whether Christianity is what it claims to be, not about how Ann worded it.
I think Ann’s comment using the word perfected is innacurate theologically, but not in error in what I believe is her possible context she meant.
To be a Christian means you are someone who has believed on and received by faith The Lord Jesus Christ and that your sins are forgiven through Him by faith.
Jesus fulfilled all the Jewish prophesies of the Messiah because He IS the Messiah. To believe in this fulfilled prophesy is to , sort of, not my word but hers, to reach perfection when it comes to what you are supposed to believe.
What she spoke of is the crux of the Christian Faith and it is not an intentional putdown or insult, it IS the Charistian Faith.
She did misspeak when saying that people can work they way through obedience to get to heaven when they die, like she said about Judaism, and she should have known that, because it is NOT Christian theology to believe that ANYONE gets to heaven through works or obedience, and that includes the entire world, not just Jews.
Her statement is NOT anti-Semitic.

The issue is whether Ann helps or hinders us when we try to win people over.
