It sounds like she is a settled hamster now. The thing is with large enclosures and deep bedding you only see a little of what the hamster is doing. It might be very active underground digging around and just not visible. If she seems healthy and is eating and drinking well and doing hamstery things I wouldn't worry though I'd definitely ensure she stays tame and keep getting her out as they can become anti social if you let them and you probably want to interact with your pet. It's also important for health checks.
