I know some of the docValue APIs changed in 4.10, because we had to re-code some custom stuff, looks like https://issues.apache.org/jira/browse/LUCENE-5882 changed the format on disk too. The comments on that ticket don't suggest an 8% increase in disk space, so maybe you are hitting some kind of edge condition which means the new format is not efficient for you...
