Grease Pencil Object (Strokes) unaffected by Background Light

Exact steps for others to reproduce the error
Open either the General or the 2D Animation default file. Add a grease pencil monkey and a basic mesh, set some background color and change the strength settings once to 0 and once to 1.
The shading of the Suzanne object stays the same. When adding a spotlight and aiming it towards Suzanne it gets lit properly.
The demo video of the grease pencil lighting shows correct black objects where no scene light is hitting them.

Don't use greasepencil-refactor branch. This is old. Use greasepencil-object branch

The gpencil world lighting only supports the world color not the world nodetree. This is a known limitation, not a bug.

Thanks for this clarification.
Switching nodes of in the world settings indeed solves it for me.

Are there plans to to change this limitation? Otherwise it might help if the default setting for the 2d Animation template would be nodes off.
