 From an inside viewpoint  through a window, the radiance distribution 
is very much stepwise in reality, isn't it ?
Your argument holds if diffracting at the window border is taken in and 
only on a very detailed scale.

It's not so  much the underlying Physics (they're quite clear), but the 
statistics of typical scenery.
