you can think of the RC updates via dealer only as system updates on your phone (eg android4>5, 5>6 etc). Since no OTA/user side update is available, it's dealer only which they do via a USB stick. The RC updates should include a full system reset that will wipe any of your changes - wallpaper, radio presets, MPG figures etc
the Honda app center updates are like your android play store downloads; individual app update only.
there is a 'system tools' updates via HAC, but thats more likely an app signature/bug fix update. ie: since apps are locked down to Honda signatures, new app signatures get updated and this package is what validates them so need updating from time to time (just a guess on this one though)
