As I understand it the new designs have far more abrupt transitions when light or color changes. The new lenses would be an ice pick and the older designs would be a golf tee. So in color or density transitions, the newer designs would more accurately record the change which would also translate into grains of silver at the edges of the transition. The older designs do not have as tight a core so at transition points there would be a smoother transition. All of this would not explain a clear sky being more or less "grainy".
