The DA and DV tags get hidden temporarily and are replaced with Ultra HD 4K and/or 5.1 even though the function of DV and DA are observed.
In order to get them to show again, this is what I did on my end on AppleTV 4K 3rd Gen.
While on the Netflix app, Using the Siri Remote (not on Netflix search), search for any Netflix title that has support for both DA and DV eg "6 Underground"
The title movie / show will be opened in the AppleTV app, scroll below and select open Netflix.
Close and reopen the Netflix app
Check for any other supported titles which were not showing the DV or DA tags such as Bridgerton, Queen Charlotte, Stranger things, Warrior Nan, 6 Underground, You etc... The DV and DA tags should now be shown on those respective titles.
However, this does not last for long. It gets reset as soon as you watch a DV/DA supported title then close out from that title screen onto Netflix home screen. Check the last few seconds of the video at 1:50.
At first I thought it’s a Netflix issue but it’s likely an Apple TV glitch that needs to be fixed.
