[noob question] is it normal for environment static lighting sky to only work outside after baking?

thirty seconds here shows exactly what i mean, when i turn static lighting sky off, it looks more like the baked result beforehand, after baking it basically doesnt matter indoors anymore whether static sky lighting is ticked on or off, it does have an affect outside

When you set sky to none, there's no ambient lighting
Baking calculates light coming from the sky, including shadowing/occlusion of it from objects
Without baking you get ambient light from the sky, but without it being blocked by walls
After baking because the room is mostly enclosed, almost all ambient light from the sky is occluded

So it's perfectly normal?
