How to query what exact assets are currently loaded in memory

When I move from one of my game levels to an empty scene I notice that a lot of memory is still being used and not cleared as it should be. In the profiler I can see that 3 mb of animations and 4 mb of audio is still used even though the new scene only has a camera in it.

Is there a way to query what are the exact assets that are loaded into memory instead of the current x mb of audio, x mb of animations data in the profiler?
