Not boring perhaps, but a little difficult to relate to. I got the impression that she was so far in advance of other children that she probably had little interest in them, other than her sister.
A peer group is part of healthy development and socialization; all the admiring adults around her would be unlikely to offer the sort of check to the ego that most of us
suffer encounter as we progress through life.
I sincerely hope she has a good, wide circle of varied friends and acquaintances nearer to her own age than was suggested by the documentary, for her own future wellbeing.
Edit: I wouldn't want a 'gift' that made me so much different from my peers.
