A set of new software updates have been rolling out over the last couple of weeks to nearly all Amazon Fire TV models. These updates remove the option to change the Dynamic Range setting on the device, which was incorrectly added with the last software update. The only model that hasn’t received these updates is the Amazon Fire TV Stick 4K, because it is the only one that can have its HDR settings modified.
Older Fire TV devices running Fire OS 5, which include the Fire TV 1, Fire TV 2, Fire TV Stick 1, and Fire TV Stick 2 have received software update version 18.104.22.168 with a build value of 630508620. For whatever reason, the 1st-generation Fire TV Edition televisions by Element and Westinghouse have received a slightly different software update with a build value of 630508520. Fire TV devices running Fire OS 6, which include the Fire TV 3 (pendant) and the Fire TV Cube, have received software update version 22.214.171.124 with a build value of NS6258/1607. I assume the 2nd-generation Fire TV Edition televisions by Toshiba and Insignia have also received this same update, but I have been unable to confirm it, as I do not own one of these TVs.
The only thing that these updates seem to change is the removal of the Dynamic Range Settings menu found in the Display options. This menu first appeared when the Fire TV Stick 4K launched in October. It was added to all other Fire TV models with software updates in December.
These settings allow customers to switch between always displaying in HDR or displaying content to match the original dynamic range of the content. It turns out that only the Fire TV Stick 4K supports the ability to change its Dynamic Range Settings. Adding the option to other Fire TV models was a mistake, since those devices don’t support the capability, so this latest update removes the setting.
