   You are mistaken. This is not about how many colors you can see, it is about   
   quality. 16bpp images can be manipulated via Photoshop without losing   
   quality over these manipulations. So after you clean up some dust etc. you   
   lose quality each time you save. With 16bpp, the loss is much lesser, and it   
   shows on the printing copies.
