Why does Windows Phone 8 build create a WMAppManifest.xml with Windows Phone 7.1 element TemplateType5 in the PrimaryToken node? The problem becomes apparent when you pin your WP8 app to the start menu and resize the tile to the wide size - there is no background image anymore.
The correct way to control app tiles in WP8 is to use the TemplateFlip element to apply a Flip tile template. There are also iconic and cycle tiles, which would have been nice. Especially the iconic tile as it is the tile that most resembles the tile created by TemplateType5.
Another upside to the appropriate tile templates for WP8 is that the large tile can be forcefully disabled.
Especially now that WP7 is facing deprecation should this problem be addressed. On that not I also hope that you will add support for WP8.1 shortly, but that's a whole other topic.
