I used to work for a major vfx house who did much work on Netflix original shows

there will be a certain amount of sharing needed between vendors, and so Netflix will need to have some vfx expertise in-house to coordinate that (similar to how a film will have a vfx supervisor that works for the film production company, who liases with supervisors at each vendor company)

but it would be very sensible for them to have an in-house asset library (which may included work written in python, not just images or textures) so that if they want to switch vfx vendor between seasons of a show it's easy to do so

in general, python rules in the vfx world. there's some c++ too. Sadly, because it's been this way for so long, many houses are still stuck in a python 2 world with huge legacy codebases
