“For home entertainment, DTS content is only found on physical media such as DVD, Blu-ray and Laserdisc – no video streaming services such as Netflix or Hulu support DTS. Sonos is focused on modern listeners who predominantly stream and because most physical discs encode DTS at bitrates substantially similar to Dolby Digital, we have decided to not support DTS on PLAYBASE as we don’t believe it offers a better listening experience for the majority of owners."
Should help answer that question.
