If I remember, I will look at mine tonight. But there wasn't a new PCC and
that indicates that TLG considers it to be the same part. How widespread has
it been observed?
It is probably just a variant. The TVA will be along to correct it.
My visor is also lower than the picture of the old one. My vote would be that
it is just a result of putting the piece back into production later and not getting
it all aligned the same. But my vote doesn't count. If an admin says to
fix it, I will fix it.
A note has been added to the entry. As this part has the same exact PCC in both
sets, LEGO does not consider the helmets to be different. I would chalk this
up to the printing setup used for making a second production run of helmets.
