Difference between "base color", "final color" and "scene color" in SceneCapture2D settings?

In SceneCapture2DComponent’s CaptureSource settings, there are options regarding “base color”, “scene color”, “final color”.

I’m wondering what’s the difference between them? I am guessing from the name that “base color” does not take into account shading information, but I don’t know if I am correct.

Base color is unlit or just the albedo/base/diffuse color.

Scene color is rendered but no post processing (bloom, color grading, tone mapping, motion blur, etc etc).

Final color is the final image.
