Netflix film on BluRay?

When will Netflix movies appear on BluRay? Or isn't that always the case?

I ask e.g. Because of the title "In the tall grass", which is apparently only available on Netflix?

DVD, BluRay, UHD BluRay, everything can't be ordered anywhere.

As far as I know, Netflix's own productions are only available on Netflix. You want to register there and pay for it. If the films were released on DVD etc. There would no longer be a reason to subscribe to Netflix.
