[General] If WH40k is a "grimdark" setting, what would "noblebright," "nobledark" and "grimbright" settings be?

Obviously the term "grimdark" just comes from "In the grim darkness of the future there is only war" and so any interpretation is just an interpretation.

For me the grimness refers to the utter hopelessness of the scenario. You are looking at a galaxy so fucked that even the idea of it getting better doesn't really exist. The darkness just refers to the painful situation they are in.

So in this context noblebright would be a hopeful galaxy that isn't screwed up. Nobledark would be a hopeful galaxy that is in a mess (i.e. there is Chaos but we have a solution that actually works). Grimbright would be some kind of dystopia where on the surface things look good but there's a hopeless rot behind the whole thing which guarantees it will become grimdark.
