This implies no indices and 100% page fill to have same size DB and GBK.

OK, now that isn't right. Only thing I can think of is that the
database actually has secondary files, does it?

As a GBK is just meta data and then the data streamed, and a FDB has
additional space requirements for indices and the fact that records
don't 100% fill the page space, DB's are bigger than backups.
