I'd wager BEAM (2016) is the first true inflatable space habitat because it was specifically designed for human habitation, and as such attached to the ISS, whereas Genesis I (2006) and Genesis II (2007) were technology demonstration prototypes. But honestly I don't know what this argument is worth.

And frankly one could argue none of them are true space habitats, yet great steps on the way to a mature version of the technology.

Not a habitat as such, but the first inflatable human-rated facility if you like was on Voskhod 2, equipped with an inflatable airlock.

Otherwise, as able to sustain human life as a berthed module of the ISS, BEAM is indeed the first inflatable habitat.

Everything else is as you say.

The BEAM module was developed by Bigelow Aerospace and installed on the ISS as the first ever human occupied inflatable module.
