As an experiment, I baked two sets of textures in SP for one model as a test for UE.
The Format for both sets is PNG 8bit. One set is under OCIO ACEScg 1.2 and the other set is a simple sRGB.
Basically, the only difference between them is in the COLOR ones as expected. And the name flags of course.
My question is:
In a hypothetical scenario where I receive an image/map with no flags.
How to know if a map/image that has no name flags was baked/color mapped under the ACEScg curve?
In other words: How to determine if an image was baked with Utility-sRGB-Texture???
