Unused Serialized Files and Assets

Unity Engine
1

I’m calling Resources.UnloadUnusedAssets once my scenes are loaded and I’ve destroyed some boot-up related stuff.

I get this:

Unloading 9 Unused Serialized files (Serialized files now loaded: 0 / Dirty serialized files: 0)

Unloading 751 unused Assets to reduce memory usage. Loaded Objects now: 20395. Operation took 6304.129883 ms.
System memory in use: 10.4 MB.

Is there any way to find out what has been unloaded and the system memory in use before the unload process?

This is on an iOS device.

Found out I can use the memory profiler (pro feature).

I’m unsure about the 9 serialized files though???
