maya2025: What is causing these two large faces to pinch?

Ralf_Reddings

The object is very simple, it does not even have edges that are too close to one another, so am wondering why are the two large faces slightly discoloured (not sure if this is what is called pinching), I tried the conform (under the mesh menu) and reverse (under the mesh display menu) commands, the issue remains.

What could be the actual cause here?

Imgur is erroring out for me. 

Did you know you can drag-and-drop images directly into your post here, and we host them?

Looks like a problem with normals. You can see the indentation at the upper part also shading weirdly.
You need to reset your normals, don't know how this tool/option is called in Maya.
