If you USB connect to the Kobo and find the book which actually arrived there. If it's a KEPUB it will have a .kepub.epub extension in the Kobo's file system. Then copy it back to a PC directory and open it in the calibre Editor, or unzip it, whatever you prefer.
Then you can dig a bit deeper.
How did you create the KEPUB? Was it with the Kepub Output plugin? Are you using the KoboTouchExtended driver? If your source was AZW3 I'm not sure what happens if you're using KTE. I thought only EPUB got transformed to KEPUB on-the-fly.
