The MY Elysium setting included some good sandbox/ideas for an investigative noir/dystopian setting if I remember correctly so the FL will probably get this right! Excited!
Likely you are correct, but being myself not familiar with Elysium and thus not able to decipher the reference, I'd just highlight that "Noir" does not necessarily equate "Dystopian", and thus, doing the latter well doesn't automatically translate well into the former.
While there is a lot of discussion (and has been for decades) about what Noir
really is about, I believe few would disagree that a major, recurring theme centres around looking at the world from an angle that highlights its fetid backside of cynicism, greed, and corruption in a suitably low-key light (SWIDT?) ... Men are disillusioned, women are manipulative; the world itself is not necessarily a dystopia
per se, but it is painted in a stark palette of naked violence, sexuality, tobacco, booze (and possibly other drugs), as well as crime and murder.
The difference between Noir and Dystopia is sort of like the difference between Bladerunner and Brazil. A Noir story can still have an upbeat ending; a Dystopian story ... can't, really; not if it's done properly.
