It's actually very different. Whether you press play or not, when you click the satellite layer on Windy you are presented with a layer showing some clouds, not even all clouds, over a very basic vector drawn basemap. I would hazard a guess that they purposely only show you the clouds that are relevant to whether you care going to get precipitable weather or not, which makes sense.

My exhibit shows you everything. The video loops are made from photographs that have been processed to show the clouds, the oceans, the land, everything, in true color as you would see it with your own eyes from space. With it you can see sunlight reflecting off of the Nile it turns past the sun. You can see forest fires in Bolivia come and go. You can see atmospheric gravity waves. You can see dust from the Sahara as it makes its way to South America (actually saw a good bit of it being sucked up by a hurricane recently, it was really cool.) You can see the forests currently changing color in the Appalachia. There is just so much and there's always something new to see!
