If you change Netflix's interface language you'll get access to more languages for both subtitle and audio tracks. I suspect there's some estimation going on to figure out what languages someone is most likely to know given a certain interface language and location. This is a somewhat common annoyance language learners run into because it's not obvious that you need to go through these hoops to get access to the language you'd like to use.
