scattering somehow "creates" light in your view from other interaction
from other light sources.

If you have an empty bag and put in it 2 g of grass... you have a bag
with 2 g of grass.
If you have a bag full of grass and put in it... you cannot see the
difference (unless you would be exporting to openexr, and it won't be
visible on your screen anyway).

To have the same kind of effect, with a white background, you might want
to had some absorption of the complementary of the scattering color.
