Simulation to real training is an active area of research and I'm not aware of it being used anywhere in production for critical systems. I have not seen anything better than the "Learning Dexterity"[1] paper that was published last year.

That was my impression as well. Maybe the idea is get the models trained in a simulation to a satisfactory level and work on transfer of the model to real world data in parallel? There's an awful lot of money going into the first part if there's no good answer to the second part right now though.
