My impression is that now Apple is offering a streaming service,
comparable to Hulu, Netflix, Amazon Prime, etc. My Sony “smart tv” will stream all the aforementioned
and much more. From what I’ve been able to understand, Apple TV can be streamed on Samsung TVs
but for some reason not Sonys. As there are a couple shows streaming on Apple TV that I’d like to try,
was wondering if it will ever be available to us Sony owners………
Thanks,

Sounds like what you are referring to is Airplay. It's true that some TVs (LG, Samsung, etc…) support airplay without any additional hardware, it is very common for Sony to go their own way. Airplay is not standard so it's not guaranteed to be available within all tvs yet. Google also currently has their own version of casting video from a mobile device to a tv.

It's extremely doubtful that Sony would ever push an update out that would allow for Airplay support. So the next way to push the AppleTV channel content (or any video from an iOS device for that matter) over to your tv might only be through a video cable. Apple's article on the process can be found here.
