Texture Equalization using normal maps/delighting maps?

 So I found this on youtube:

I don't think the results were good but is there any chance of this method giving good results?  Anyone tried this technique at all in some advanced form? I have also heard of using hdr map lighting to remove lighting from textures.

I am wondering if there is a way to calibrate a delighting map from a texture photo and use that to remove the shadows and highlights. Anyway this can be done for photo textures?

You need to take a reflection probe of the location of the sample then bake a lightmap to the mesh and proceed to subtract the lightmap.

How is the lightmap subtracted? Is there a software for this? or can be done in Photoshop?

Compositing software that is capable of mathematical operations upon pixels.
Some examples would be Nuke, Substance Designer, Shazzam, ShaderFX.

Thanks for the info. What about After Effects or the Unreal engine material editor? Anyone knows if this is possible with the blender compositing window? Googled Shazzam. Seems like their website is down atm? Is the shader editor free?.Thanks.
I am researching this at the moment. If anyone has any info about the workflow or tutorials for this technique with the softwares. Pls don't hesitate to share

Another delighting method from Stars wars battlefront using Photoshop Camera raw and object space normal map. He also mentions the first youtube video I posted above.
