A lot of the global images of clouds (like this one [1]) are actually made from infra-red images, as making a visible composite is difficult. This means that they can only see high, cold clouds, so you only really see storms.
For example, the GOES-17 image shows large amounts of cloud off the western coast of South America. This is completely missing in the composite video, as it is very close to the surface and so almost invisible in the IR (it is close to the same temperature as the surface). About 2/3 of the globe is cloud covered on average [2].
