I think creativity is subjective, and therefor there are no right or wrong answers. Based on this, your daughter's teacher may have not communicated her point in the most effective way.
Maybe what she could have said was "I'd like to see her expand on her creativity a bit more" or something similar. To say she's not very creative, however, is the same as someone saying "red is the best colour." There is no "best colour" ...one's person's favourite may not be liked as well by someone else. Subjective
