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

It will always have a correct +/- DC voltage.

Yes, but obviously with an earthed public supply a full wave rectifier
implies that neither + or _ terminal are anywhere near earth DC potential (and
approx equally distant from it). Of course, as the live input is at the same
*average* potential as neutral it is not going to make a difference to the DC
output level which way round you connect the supply.
