Not necessarily.

Different parts of the image may lend themselves to different compression 
techniques and file formats. Separating a part of the image that has more 
detail or a different colour palette can mean the rest of the image can be 
compressed much more efficiently. But it is better to separate into layers 
rather than slices.
