Am I correct in saying that it does not matter if there is a LN

Correct...
It will always have a correct +/- DC voltage.
Yup.
In fact if you are designing DC powered kit that runs from an external
supply, then sticking a bridge rectifier on the input even though you
are only ever expecting DC rather than AC, is a way to ensure your kit
will never see the input polarity reversed if used with the wrong PSU.
Same applies to data. The Army's FAM - Field Alert Monitor - starts with
a bridge.
