Is there any way to check if Texture has preset values?

I can’t find a way to check if a texture has the same preset values. I have excluded all properties except one in order to test it, with Platform Settings and texture settings without success, even with DataEquals and Texture or the TextureImporter object from: Unity - Scripting API: Preset doesn’t seems to work. Is there a way and I’m missing something or for the moment is not possible?

Same issue
DataEquals always return false on a Texture, even after applying dozen of times the same preset
