Amazon Prime app has always reset HDR to default settings True Cinema, with Normal colour temperature.
I have my settings in Cinema equal to True Cinema, so switch to that when viewing HDR in Amazon.
It does not affect the True Cinema settings on the tv, just whilst in Amazon.
I can't see any differences yet with the new firmware update.
Thanks for the reply bud, but in this instance, not helpful I'm afraid!!
The Prime Video app hasn't always done so using "true cinema" with "warm 1" or "warm 2" temperature either. Both are exactly how I had my TV configured prior to this recent update without ever experiencing any issues at all in the past, hence my question. My preferred settings have always previously been retained for Prime Video/VoD across multiple updates for some years now.
I routinely use the Prime Video app & today was the first time it has ever presented a problem.
Yes, also aware that the TV saves the individual user settings for SDR & HDR for each individual HDMI input & VoD/apps. They're not affected by the update & neither are other apps such as Netflix, it's just Prime Video that has suddenly become an issue.
For whatever reason, apparently your TV has always had a problem with Prime Video correctly retaining certain display settings, whereas mine has been fine since new & only became affected with the new 3.239 update nearly 2 weeks ago !!!
