I know of no other reader besides Calibre that shows much of anything other that title, authors, and date but ... there are so many generations of readers out there now so who knows. The original reason for these other metadata fields was as search fields that are meant to be used to help catalog and index ebooks. Overly complex html/css can actually impact searchability, which is the primary reason for "metadata", but to each their own. As long as you keep things well-formed for xml parsing, you can put anything you like.
