understood..
my point as stated, was that the options and settings in my 2018 Sport, were vastly different from what was posted above my post.
it's possible that in 2015 these were just place holders in the programming for future features/options/settings, and the features like the HUD operated independent of them, therefore checking or unchecking in your car does nothing.
In my car there is a response, and near as I can tell it is the same response as if I went into the cluster and disabled the HUD from there.
unchecking it in the dealer menu disables the HUD, then in the Cluster settings, the HUD shows disabled. and if I enable it in the cluster, the checkmark comes back in the dealer menu and vice-versa, so the two are tied together in my vehicle, so Hyundai changed something between 2015 and 2018.
Also Parking Assist 0 and 1 are both checked in mine, and unchecking 0 disabled my front sensors, unchecking 1 disabled the rear.
