New unit just arrived today, and the first thing I checked is how much better s the home share streaming over the previous Apple TV 4K (2021).
First, it is much faster, loading and streaming HDR10 or HDR10+ files vis WiFi-6, with my files on a NAS and controlled by a Mac Pro 2019.
HDR files as large as 50GB can now be streamed using the Apple TV 4K 2022 without any issues. The 2021 Apple TV 4K cannot stream files this larger than 25GB without pauses.
A quick check shows all the streaming services are rock solid, and the HDR picture on my Sony 83" 2021 4K TV seems to be slightly smoother than the previously Apple TV 4K.
Youtube 4K seems good.
Will upgrade to TVOS 16.1 later.
So far a better Apple TV 4K over the last models.
BTW. lighting remote works with 2022 Apple TV 4K as well.
