You are correct. However, many in-studio tools are written in OpenGL. These tools are used to model objects and layout lighting, scenes, etc. by artists. They are written in OpenGL, usually on Linux. (Source: I work with several people who formerly built these tools for well-known studios like DreamWorks and Sony.)

Of course, but that’s not what we are discussing. The context for my comment was regarding offline rendering and render farms.
