I read a lot about Sony’s botched implementation of Dolby Vision but often it seems to be an issue with the built in Netflix app it’s not a panel / processing issue that I’m aware of as it can be ‘fixed’ by an Apple TV. Dolby Vision is Stunning on my AF9. I don’t think There’s a technical reason that older TVs with 2019s processors and chipsets can’t be updated to run newer stuff. But all these airplay 2 feature have an asterisk that say they will come to this years TVs at some point with a firmware update so if it’s not ready at launch I hate to think how long any updates (if any) will take. I have read elsewhere that the A8s Oreo update is any week now and this year they want to move the A8 to running same code / back end as the A9 and newer systems. But that did come from a forum so take it with a grain of salt. --- Post Merged, Jan 9, 2019 --- It’s worth pointing out that even if there are plans to update older TVs they will be keeping quiet right now to put the focus on the newer models. Sony haven’t said they will do it but haven’t said they won’t either. We’ll just have to wait and see.
