Profiler got 2 Texture2D fields ?

Hello community ! I'm currently investigating the memory usage of my application, and I can't find the difference between two fields of the profiler (since they are the most used in my application, It's fairly annoying). There is a field name SceneMemory -> Texture2D and another named Assets -> Texture2D. In there, i can find my skybox, and several other textures. But what is the difference between those 2 fields ?
