For example, I convert from epub2 to epub3. The embedded metadata shows the format version to be 3.0 (as it is now an epiub3), but the opf file still says 2.0. I don't even know how to update it as even running "polish" to embed the metadata does not seem to effect the opf file.
The OPF file in the library is used by calibre. Any changes to the metadata through calibre will update this. Don't worry about it.
