Unfortunately, I do believe that WMI has a significant effect on how one does in a traditional school setting. Being able to memorize those facts and regurgitate them is what the teachers are looking for, it's how a lot of the tests are set up so the teacher can make sure the student is learning the info. I can see how a super smart kid with not a super high WMI might get frustrated sometimes.
I was frustrated with that myself. I didn't really come into my own until the upper level college levels. That's when they were really asking to see what you could do with the information as opposed to how you memorize it.
FYI, I felt stupid when I was your daughter's age and when the principal told me of my IQ report, I actually thought he was lying.
On the other hand, by the time I got to college, I had several professors who really took me under their wings and it made all the difference in the world. I'm glad your daughter has a great GT teacher!
