First off, it seems you should use the same zoom level. The one with the smoothed weather is zoomed in almost twice as close. I clipped out sections from each map that surround what I presume are the same airports. They're pasted on the side. The one with the smoothed, more detailed weather is nearly twice as big as the other. Also, look on each map for the highest obstacle altitudes. They're different, which would seem to indicate that the map sections depicted are different, and (again presumably) from a more detailed map in the bottom one.
