As if adding ads earlier this month wasn’t disappointing enough, Amazon Prime Video has now dropped Dolby Vision HDR and Dolby Atmos surround sound audio unless you pay $2.99 per month to remove ads. The change was first spotted by 4KFilme and has been confirmed by an Amazon spokesperson. If you’re watching Prime Video content with ads, the best high dynamic range format you’ll see is HDR10+, which is comparable to Dolby Vision. However, it’s quite rare for content to be available in both Dolby Vision and HDR10+, so, more likely, you’ll see the inferior HDR10 format replacing Dolby Vision. Similarly, the best surround-sound audio format you’ll hear is Dolby Digital 5.1 audio. While this change will probably push some people to pay more, it may also be cutting costs for Amazon in terms of licensing fees to Dolby. Amazon made a similar cost-cutting decision with the cheaper Fire TV Stick Lite, which cannot decode Dolby audio, while the regular Fire TV Stick can decode Dolby audio, even though both streaming devices share identical hardware.
