There is no definition of "enhanced ePub3" in the official ePub3 specs. Many publishers use "enhanced ePub3" to refer to interactive ePub3 text books generated by Apple tools.

Most likely the Ingram people themselves don't know what "enhanced ePub3" is. IMHO, making ePub3 books a requirement doesn't really make sense for publishers, unless they specialize in interactive ebooks.

Post a list of the ePubCheck error messages that you got for the original ePub2 files and the ePub3 files.
Some errors can be easily fixed by running a simple regex search in Calibre and/or Sigil.
You might also be able to address these issues by modifying the source files that you used to generate the ePub2 files with Calibre.
