On January 29, Amazon started showing ads to Prime Video subscribers in the US unless they pay an additional $2.99 per month. But this wasn’t the only change to the service. Those who don’t pay up also lose features; their accounts no longer support Dolby Vision or Dolby Atmos.
As noticed by German tech outlet 4K Filme on Sunday, Prime Video users who choose to sit through ads can no longer use Dolby Vision or Atmos while streaming. Ad-tier subscribers are limited to HDR10+ and Dolby Digital 5.1.
