Natural light is no back/front light, and only using environment light, like a spot, room light, night light, or open curtain windows shining daylight into the room.

Ok, that isn't the normal definition of "backlight" but it works well enough now that you've defined it.
I do think that your front light (external to screen) and your natural light are basically the same since you include a "spot" light as an option for natural light. This could be anything from a dedicated reading light to no lights at all to daylight. Too much range to be useful. The position of the light is so variable even in your examples that it really doesn't seem like it can be generalized.
