Imagine someone opens a box with a new iPhone 12 inside. Out of box it came with iOS 14. When the phone gets upgraded to the latest software, does it automatically gets updated to the latest one, or will the software get upgraded incrementally (14 to 15 then to 16…..)?

Not sure about IOS, but in android, for most devices, over the air updates are usually incremental: as the patch only contains the difference between the previous and immediately next build, each patch must be applied sequentially. If a user is behind on updates, this can meana pretty long reboot cycle.
Many manufacturers also post full system images as well (and sometimes make them available through the OTA mechanism as well), allowing the current version to be flashed even if the currently installed OS is outdated or missing.
