Spotify Connect bitrate options

You know how one can select the streaming quality in Spotify in iOS

Normal (96Kbps)

High (160Kbps)

Extreme (320Kbps)

Yes, I know, it's laughable (who on earth 'approved' those labels?) But anyway, I am digressing.

The Q here is: Can we safely assume that the Bitrate for Spotify Connect in our streamers will be set to .... "E X T R E M E" ? i
