6Mbps is Twitches recommended ingest bitrate, and their highest quality just serves the ingested stream back to viewers without transcoding. In reality the storage would actually be a little higher still because they have to store all the transcoded lower resolution versions as well.

Interesting, I wouldn't have guessed that it would make sense for them with regard to bandwidth cost. TIL, thanks.

It's a trade-off between bandwidth and encoding capacity. Twitch actually only guarentees transcoding for "partnered" streamers above a certain viewership threshold, so when watching a smaller streamer you might only be able to view the "source" quality if there isn't enough encoding capacity to go around.
That makes sense.
