All materials and textures being loaded into scene even tough its empty

Currently on Unity 2020.1.6f1, but happens also on the 2019 versions

Even tough i'm on a blank scene (no references to prefabs and not else at all) ALL my textures and materials from the project are being loaded into the RAM as shown in the profiler.
I made a build to the android to test and the memory is indeed being used.

What may be causing this? is this a unity bug?
I searched for topics related but didnt no found anyone with the same problem.

You can see it on the screenshot.

 

Do your textures and materials happen to be stored inside a folder called "Resources"?

 

No, the Resources folder does not even exist since all my objects needs to be store in memory. (Remembering the scene in question shown in the screenshot is blank, no scripts and no references AT ALL)

And even if they were i believe a script should call Resouces.Load for them to be loaded to the ram.

 

Took a look at the editor.log of the build and the textures seems to be coming from the URP, says its 4.4mb in the build size but strangely the profiler shows over a thousand textures and 103mb
