Good points above.
Some more thoughts:
1. If jealousy and unhealthy competition are major issues in the sibling dynamic--for whatever reason--obtaining IQ data will not change the dynamic for better or worse, it will just provide a specific catalyst or focal point for it. In the absence of IQ data, some other catalyst or focal point will fill this role.
2. It may be that what is manifesting as jealousy and competition are actually insecurities that might be partially assuaged by IQ/achievement data that documents objectively your daughter's strengths. It may also be that there is a second exceptionality that undermines her confidence in her own abilities, due to the inconsistency between what she feels she ought to be able to do, and her actual performance.
EDIT: Oh, and BTW, I was a younger sibling assumed to be not GT by my parents, until the evaluators for my older sibling asked if there were any other children. I was just much better at masking.
