Supposedly, you can SEE all areas the same in all versions, but pay versions have higher resolution printing options.
Some areas just have not had high-res photos taken yet. You'll notice the color change as you move from a high-res urban area to a countryside where cows are not worth imaging. There is gradual upgrading as time passes.
My house shows fine, but many more rural areas are not considered high priority....and certain potential military targets are pretty well blanked out. My father's hometown of Lost Springs, Kansas, is several levels less detailed than my house in a DC suburb.


There are also a few places which have managed to get their sites declared 'sensitive' and not available to good resolution.
