Does anyone know where to find Apple TV app apk for Android TV sideloading that is not the variant meant for Amazon Fire TV?

According to Apple's website, the Apple TV app (for Apple TV+ subscriptions) should other than Amazon Fire TV also be available on many Android TVs from Sony, including Sony Z9G Series, Sony A9G Series, Sony X950G Series, Sony X850G Series and more which all also run Android TV natively. Has anyone managed to get Apple TV app apk from one of those?

I have tried to sideload Apple TV (Fire TV variant) apk from APKMirror on both my Philips Android TV and on my Nvidia Shield TV. The app meant for Fire TV looked to install fine but then when launched only get a message saying that Fire TV first needs to be updated before it will run.

I have previously sideloaded the Amazon Prime Video apk on this same Philips Android TV (and also updated it several times) and that still runs fine.

My backstory is that I got a 12-months Apple TV+ subscription with my new iPhone and I would like to install use the Apple TV app apk natively on both my Philips Android TV and on my Nvidia Shield TV. I do not wish to use workarounds like casting or using an AirPlay app on my Android TVs, neither do I wish to buy an Apple TV or an Amazon Fire TV.
