Why these themes are hidden in windows 7:

You may be a question that why windows 7 keep these themes hidden  from us so the answers is that i think because during installation of  windows 7, you selected your country so windows 7 give you data specific to your country for example if  you selected your country as "United States" So it will  give you only the themes and wallpapers that are related to 'US' But you can  also use the other countries themes if you want as we discussed earlier.
