The simple answer is yes, round ended liner pins were not used in WW1 German helmets. (I can't say if this is true for WW1 Austro-Hungarian models).
These are the round-ended repros I'm referring to:
Original pins have clipped ends and corners, whether they're cut straight across or not. These pins are faked too however. The round ended ones are just easier to spot as fakes.
I would say they are not all fake.
It is hard to say, perhaps comparing the size (In mm/In)
I saw also original round ended liner pins on hemets which were not faked.
