Display Mode to hightlight geometric changes?

So I do quite a bit of work with annotating scanned real-life objects, and the annotation part of the workflow is done in Rhino. Occasionally I’ve found myself wishing for a Display Mode, that would highlight geometric changes on the mesh surface - particularly to locate wear or tool marks on the surfaces. I’m thinking of something like a height or slope map, but for a 3d object. Possibly something that would colour code angular differences between polygons?

Does anything like that exist, either as an analysis tool or plugin?

Edit. so far, I use either the shaded view or rendered view with increased glossiness on the texture file, to make the surface geometry pop out. But that method is dependent on the kind of light source that’s used and the angle of the camera relative to the object.
