As I mentioned in my previous post I compared the PKG and DMG updaters (omitting the firmware update from the comparison).
Delta updates are really the same in both forms.
Combo updates differ quite a lot, with the differences being almost exclusively related to language specific resources. In short, the OSXUpdCombo10.11.4Auto.pkg doesn't contain many non-English resources while osxupdcombo10.11.4.dmg contains a lot of them. Perhaps the non-English stuff is downloaded on-demand - depending of the actual system locale..? See the attached diff-OSXUpdCombo10.11.4Auto-OSXUpdCombo10.11.4.txt for the full result of the comparison.

I don't think it's worth the effort since Apple didn't release the recovery update as they normally would. The last recovery update was released in December along with OS X 10.11.2. Since then there was none and we had 2 more OS X point releases already. While they might have updated the recovery content (didn't check it), either they forgot to release it as another update, or the changes were minor and simply not worth it.Don't forget to update the recovery partition as well. ...
