If you search for exact title matches https://www.imdb.com/find?q=Arrival&s... you find that there are three movies with that name released in 2016. The Roman numeral is added only if there is a match of both title and year. There are fifteen movies called Arrival but the highest Roman numeral is IV in 2012. In 2016 there were three.

you see there was a Short by the same title in 2013. That has the Roman numeral (I).
Theh 2016 feature film gets the (II) designation.
