If Discovery was some random new IP with a small devoted fanbase, then you could make at least a semi-reasonable hipster accusation. Star Trek hasn't been 'cool'...well, ever? If Discovery ever became a huge critical darling, maybe.
But in general, anyone who accuses other people of being a hipster for liking something less popular than the stuff they like is just trying to delegitimize other people's opinion by attacking their motive for the opinion, and is thus, a jerk. The artistic version of calling them an SJW.
