Where are you getting this information? Not only have I never heard of this, "the major VFX vendors" don't really do 'virtual production' or previz, with the exception of the ILM stagecraft stuff.

I haven't heard of anyone using unreal for final frame rendering in film.

I think they're overselling it, but Unreal is fairly heavily being used in the early parts of pipelines at various studios, certainly more than Unity engine itself...

i.e. MPC had significant use of Unreal on set for mocap, Framestore has Unreal setup for previs and mocap (they hired some ex-games devs with Unreal experience to work on it)

ILM stagecraft is the 'hero' example (and as mentioned, they've got Helios now), but various studios are experimenting with it in various departments.

Disclaimer: I work for Weta, and above doesn't reflect anything about Weta (Gazebo, etc), it's all from friends/ex-colleagues at other studios...
