It seems that there is still a lot of confusion about the "volumetric cloud" claim by DF, so let me just repost the screens that I shared back on era.
As you can see below, the clouds have no geometric self-occlusion when the camera angle drastically changes, and the rotational parallax is consistent with billboarding (pay attention to the bottom of the croissant shaped cloud):
With an actual volumetric cloud, it would be physically impossible for the bottom of the cloud to still remain visible after going from a head-on view to an overhead view. The only explanation is that they're not actually volumetric.
That being said, the shading dynamically changes with respect to the camera angle, so it does give the impression that you're looking at different sides of the clouds as the camera angle changes, but you're not; it's just a very good illusion when combined with the blended billboard transitions.
As for the talk about BOTW 2 being too strong for the Switch, please, let's not do this again...
