Metroid 3 Graphics Comparison

Gamespot has this feature up comparing the graphics of MP 2 to MP 3. Pretty interesting. I know that the Wii isn't a graphics powerhouse, but I've been disappointed that developers don't even seem to be trying to make the games look nicer. Just one more thing to enjoy when I finally start playing this one. For those of you who have played it, are the updated graphics noticeable, or do they even matter?
