During my time in that world, I never witnessed an actual genius like you would have in fiction and exceedingly more rarely in reality. So, I don't know how one would be treated in reality. It seems quite inefficient to make a genius do the kind of work that won't foster their talents if everybody is expecting great things from the genius. Like you said, some freshman manual compiling and translating from a foreign language could be annoying for a researcher, but it would be pointless for the genius. I guess she was just hitting on him by doing favours, so it wasn't meant to be anything impressive.
