As part of a firmware update, Sony has started rolling out the Apple TV app (TV+ and iTunes movies) to its 2020 and 2019 TV line-ups. High-end 2018 models are also getting the app.
Update: Now also available in North America.
TV+ and iTunes movies
When Sony brought the Apple TV app to its XH90 (X900H) model in October 2020, it promised to also bring the app to its 2020, 2019 and select 2018 TVs in "over 100 countries and regions" before the end of the year. 

Well, here it is. Firmware v6.4960, which is rolling out now in Europe and coming soon to North America (update: now also available in North America), introduces the Apple TV app widely across Sony's TVs from the last few years. As far as we can tell, this includes all 2020 Android TVs models, most 2019 models (but not AG8, XG83, XG81 and XG80 at this time), and two high-end 2018 Android TVs (AF9/A9F and ZF9/Z9F). The full changelog and a list of compatible TV models can be found at the bottom.

The Apple TV app provides access to the Apple TV+ subscription service with shows like The Morning Show, See, Defending Jacob and Ted Lasso, the full iTunes movie library (including all 4K HDR titles), and partner channels.



Sony has confirmed to FlatpanelsHD that the app supports streaming in 4K HDR and Dolby Atmos on compatible TVs.

Sony's new firmware also streamlines the user interface across the 2018-2020 Android TVs and includes various bug/performance fixes. And if you own the ZG9/Z9G, the firmware even includes HDMI 2.1 4K120 support.

In addition to Apple devices and Sony TVs, the app is available on select LG, Samsung, Amazon Fire, Vizio, and Roku TVs and devices. Follow the link for a full list of TV devices with the Apple TV app, AirPlay 2 and HomeKit.
