The Workbench engine seems also to use filmic. I was always wondering why the studio lights view look so washed out - this is the reason. It makes it unnecessarily hard to spot details in the mesh. Also Matcaps should be already colormanaged(?) so they look wrong too when using filmic.
Yeah, this is an issue, especially the low contrast default shading. But not quite a simple to solve I don’t think. Matcaps actually look better with filmic, otherwise the highlights get cut off in ugly ways.
I think this is the way to go. I adjusted the default studio lights a bit to be similar to the current default but with more contrast. It’s quite usable now - maybe it can be used as a starting point
