Clarification: "size of the whole ISO directory tree" means the size of the meta-data, not the size of the data files in the tree. The meta-data in Fedora-Workstation-Live-x86_64-31-1.9.iso are very small, because there are very few files in the tree. Adding a text file of a few hundred bytes yielded a growth of 393216 bytes.
