I do believe many game developers were lazy, however there is some good reasoning behind it.
It's well-known that the Wii sold the most consoles, however when you take the individual person on the console, those with Xbox 360s and PS3s bought more games for their system than Wii owners, more software quantities ship on the other two consoles than the Wii so in some respects dedicating more resources to 360 and PS3 games is more profitable.
The Wii exclusives tend to push the graphical power of the Wii greatly, so we know it's possible, it's a shame when you see the PS2 graphic style shovel-ware the console has compared to mario galaxy.
The Wii's low console power also meant that realistic graphics that people were used to on other consoles could not be translated to the Wii, some of the most impressive looking titles have distinctly cartoony effects, Mario Galaxy, Brawl and Skyward Sword, when you take something like Goldeneye Wii which strived for realism, it sadly missed the mark with the low quality character faces and textures, making up for it mostly in the animation department, so in part if you're trying to make a realistic Wii game, it's somewhat not possible considering the competition it stands against with the other consoles, you could say that developers chose to create something that simply works than to attempt to match these other consoles.
One distinct feature that the 360 and PS3 have above the Wii is their software's expandability, games can be patched, updates, new levels, unlocks can be added in, so there's money to be made from those too, dedicating more resources to those consoles could prove profitable over a long period, whereas the Wii takes the old approach of releasing software into the wild to fend for itself, so one bug in the software and it's all over, meaning more resources would have to be dedicated to bug testing for Wii software, which is more time and effort, so perhaps relaxing time spent on the graphics and gameplay lets the bug testing be more thorough to produce software that is solid, even though it's not using the console's full potential.
The Conduit showed that when effort is put into it, a Wii game can look great and achieve the complex effects that the 360 can do, but so much effort was put into that game and when compared to the sales it made, was it really worth it?
