It’s not a super descriptive term for sure, but I have no idea what it would be called otherwise. It’s similar to things like Metroidvanias or Soulslikes in that it’s a very specific niche without a clear delineation of what it is, but fans will know it when they see it
I’ve never heard the term “immersive sim” before, but if Half- Life, Deus Ex and Thief are examples, then sign me up.
Bioshock, System Shock, and Dishonoured are also examples.
Prey (2017) is another example.

When I hear immersive sim I think of Arma and not Bioshock.
I don’t know how sim plays into the genre.
