there tend to be leftover files / data from previous versions, so finding the correct version information can be a bit trickier than you might imagine, also for some games there are plenty more build date strings in files, sometimes newer than the build date that is displayed / the main code build date simply because of how the build / deployment system worked.
in other words, without them booting, it's not actually that easy to know which dates will be shown for a decent number of the hdd based games.
