Have you seen both in the same town at the same time ?
If you know how to dump ISOs and extract archives, there are some interesting files on the game disc in the "Str/Brres" folder
Code:

These appear to contain the graphics for the buildings and other things seen on the world map (ie. when outside a house). Different versions of the game as well as language, and season ("S" for summer, "W" for winter)
The NPC house texture data is stored in there as well. The exact logic is not understood, but it should be possible to patch these for custom looks (IN YOUR TOWN ONLY - it won't work over WiFi). Possible but a lot of work for little gain IMHO.
