Ability to reproduce what you have learned is brilliance, if students go to class, they were taught the same way and only a few came out with first class in the entire class after writing the same exam/test. Those exceptional students are brilliant.
But the genius are those who can use their imaginative power to create new concept that has never existed before, they question the status quo.
Albert Einstein had many brilliant classmates, but he was the only genius among them.
I hope this helps.
Brilliant: premise → logic → conclusion
Genius: premise → conclusion → proof
I think that it will be.
