I think we both know what game you mean and I’m carefully avoiding being labelled as a copy. 
Nobody that I’ve seen is cel-shading this way yet so I end up dumbing everything down when recreating effects, whereas if you enable the entire suite you get a much richer result. It doesn’t just draw hard lines - almost all of the subtle detail in the screenshots above is coming from the celshader as well.
I think you’re right though, it could use more examples.
