I had a programming languages survey class in college. The thrust of the course was different languages for different applications. It's not startling that the person, whose comment you quoted, doesn't find the functional paradigm helpful in graphics programming. Functional programming helps with expressiveness and reasoning, i.e. variables don't suddenly change on you when you're not expecting it.
A video game programmer would probably not be helped because a big part of their coding, as I understand it, is wringing out every clock cycle and byte of memory possible. However, the programmer writing the AR/AP system that allows tracking for in-game purchases would find OCaml, for instance, very beneficial.
