Can anyone check if Atmos or Dolby Vision is available on the forms of getting the prime app (firestick, shield, etc) , maybe we're just getting shafted as C9 owners.Not anymore you don't. Amazon appear to have dropped both Dolby Atmos and Dolby Vision from the few titles that previously included it. You no longer get Dolby Vision in association with Jack Ryan (series 1), Bosch (season 2) or Suspira if accessing them via the Amazon app on the C9. You now only get HDR10 in association with these titles.
Similarly, you no longer get Atmos in association with the first Jack Ryan series, Carnival Row or Suspiria.
