When the dash is open the launcher and the panel also gain blurred backgrounds but when the dash is closed revealing the launcher from the left edge shows launcher with no blur it can be less attractive in some cases and also reduces the visibility on the BFB with certain desktop wallpapers.
in the attached screenshot the launcher is transparent+the desktop wallpaper gradient, blur would look nice.
