It sounds to me like she's shy but veryfriendly, especially since you haven't had her long. Somerabbits never like to do much when they are in their cages, but itcould also be related to the size of her cage or if it has a wire orslippery bottom. Or she's not interested in the toys shehas. When Loki was at the humane society, he had a wire floorand a litter box. He rarely left the litterbox because hedidn't like the floor. And he didn't have anything to do inhis cage, anyway. Many rabbits don't seem to mind a wirefloor, but he hated it.
As for whether that's what her personality is really like, you will find out in time.
