* Improves general performance of the TV
* Resolves an issue where TV freezes after update
The release notes for the U.S. version state:
* Fixes an issue where the TV will not respond to the remote
* Fixes an issue where the TV freezes after performing an OS update
So perhaps we already have these updates in the U.S.?
EzAV, did you update your Apple TVOS version recently or anything? Just wondering if there are any other variables at play here or if all of the improvements came from the v6.6555 firmware update on your A8F?
I think it's definitely possible (and probably likely) that the U.S and U.K have already received this update for the A8F.
Apple TVOS is at 13.4 and was updated as soon as released, so no recorded change there.
What I find interesting is that when activating ACE the A8F used to leave it active when changing from HDR to SDR content, and you would annoyingly have to go in and turn it off.
eg. In Cinema Pro I used to have it set to low with Gamma +1 for HDR10 content then when resorting to SDR it would still be active but Gamma would change back to -1.
So I created an identical profile for Cinema Home for SDR content then would switch to Cinema Pro when HDR10 was required.
Now though, it remembers the ACE settings for SDR, HDR10 and DV content. So I just sit in Cinema Home for SDR and DV content and switch to Cinema Pro when using HDR10.
I also find that ACE basically has little to no impact at all when adjusted through the internal apps on DV content.
I have always left it to Off anyway as my understanding of DV content (and benefit of such) was the scene to scene Metadata analysis, thus negating its need.
However activating ACE through HDMI now though for DV content on the Apple TV4K really seems to unlock the TVs true capabilities for this content.
ACE never performed as well as this for me previously, DV content through Apple TV4K underwhelmed.
Now, I honestly feel like I've received a new TV as the improvement to me is startling. It feels right to me now. I can't see any artifacting but defer to the experts on this. Just ask that you try it.
I have theories for this - such as what as been previously suggested ie. A9G having a DV Bright and DV Dark mode
but also because perhaps with DV IQ on the horizon, and Sony more likely getting on board early (and avoiding their DV release fiasco with 2017, 2018 sets) that
a new DV profile has been created and issued to Apple for the Sony 2020 sets. Thus to be backwards compatible with previous models, (the profile itself, not DV IQ), a firmware
update was required and may have boosted the performance of the older sets. Again just a theory.
