GPU Lightmass and World Settings - Lightmass Settings

Have been using GPU LightMass for a while but still unclear about one thing.
Are the settings in World Settings-LightMass Settings ignored when GPU Lightmass is used?

Yes, the world settings lightmass settings are reserved to CPU baking only.

Lightmap compression and the volumetric lightmap settings work

Otherwise everything else is pretty much ignored, both in the world settings and object settings, and some light settings.
