Okay guys. I did a bit more testing and came to this conclusion.
It is not through a Google app update. In fact, the Google app has the Assistant all along ever since the Pixel became a thing. The Play Services update removes the requirement to have a Google Pixel device in the build.prop file.
However, it is still dependant on your Google account, as switching between accounts rendered different results. My main account caused the Google Assistant to pop up while the other just pulled up the Google Now feed, with no options to toggle Assistant.
TL;DR version: It's a server-side thing, dependant on your account.
