Do you have any idea what percentile her scores place her at?
It's possible that if she's in a school setting which is flexible and supportive, and her scores aren't too far out there (that is, 95th percentile, not 99th) that she's perfectly happy and well-adjusted because her needs are being met pretty well.
It's not necessarily the case that she is "less" gifted, either; it's also possible that she has found some adaptive coping strategies that just work really well for her in light of her own learning style, needs, and personality.
