What's the default material values?

What’s the default values for all the material inputs?

I know these:

BaseColor = 0,0,0
Metallic = 0
Specular = 0.5
Roughness = 0.5
Emissive Color = 0
Opacity = 1
Opacity Mask = 1
Normal = 0,0,1
Ambient Occlusion = 1

But what about the others? I haven’t found their default values in the documentation or when I search for it.
