Dolby Vision content displaying distorted since tvOS 12.4 update.

I have this problem also. It seems to happen in dark scenes when playing Dolby Vision movies during dark scenes. I am unable to watch movies I have purchased because of this.

My Tv is a LG UH850V. It has worked OK previously before. So I assume something has updated to cause this issue.

I am still having the same issue using TVOS 13., in both the TV app and the movies App. Interestingly it even occurs in the trailor for Apple's own new series "For All Mankind"

I have raised this with Apple support, and suggest that everyone else might like top do so?

I have raised the issue with Apple support also, just waiting for them to reply.

When watching a Dolby Vision show on the Netflix app, everything appears to work as it should. So something iffy is happening somewhere with Apple content and Dolby Vision.

I spoke with support a week or so ago. They were sympathetic to the issue, but suggested they could not do anything there and then, but would put in a report. It will require a TVOS or a TV update to fix and all they could suggest for the meantime was a work around of using 4KSD and switching off HDR matching for DV movies, which I'd already worked out for myself :)

Hey bro I have same tv as you and having same issue 👎👎 have you found out what is causing this problem as all my moves are shown in Dolby vision which are tv is supported but when watching dark films is just distorted, worked fine previously, thanks

Hi mate, no all I can say is I’ve narrowed it down to be an iTunes movies Dolby vision codec issue. I’m aware that Dolby made some changes in the last 6 months or so to fix other issues with hdmi sources. Since our TVs have no problem displaying Dolby from the Netflix app running on the Apple TV, this seems to indicate that either the Apple TV app or the iTunes movies are not using the correct Dolby Vision codec. As I wasted half an hour on hold to Apple support and both iTunes support faults I logged were bounced back telling me to call Apple support I have resigned myself to the fact that I’ll have to watch my movies in HDR until Apple consider it worthy of an update. Pretty poor after investing hundreds on 2 Apple TV’s and a ******** of movies in the last 2 years believing it was the best way to build a 4K library.

Remember that if Apple aren't aware of the widespread problem, they will certainly not fix it. The more people that report it to Apple Support, the more likely they are to spend resources fixing it? When I phoned, they had no other records of it having been raised (or at least they couldn't match up similar reports), but he did find these posts (which Apple do not watch)

Useful to know that it isn't specific to LG TVs, and is affecting quite new models as well.

Apple need to sort this out as there is no point in my buying more DV movies from iTunes until it is fixed....which means anything 4K as most of the new 4k movies seem to be in DV? I've noticed that this also affects the DV content on Apple TV+ when I watch the trailors

It seems to be TV related and the question is why processing Dolby Vision content on some TVs isn’t working correctly with the Apple TV implementation of content they are streaming but it does work with with Dolby Vision content outside of Apple TV...

Watched, or tried to watch, “for all mankind” on ATV+ last night and The number of distorted scenes was far greater than any movie I have. Thinking I’m going to have to move to Netflix for all future purchases

I have a 2018 TCL 5 Series and get the same issue. I have the Apple Tv 4k connected to an Onkyo Dolby Vision compatible receiver.

I do not get these issues in the built in TCL Apps or Apple TV's Vudu App, I mainly started noticing it when I attempted to watch SEE, and it's happening in "For All Mankind" too

Thought my tv was breaking, glad I'm not the only one getting the issue.

Just chiming in to say that I have this issue on a Philips 55PUS7304 television. I'm using a high-speed 8k Belkin cable in order to eliminate cable speed as a factor. I'm not seeing the distortion on the TV's built in apps for Dolby Vision content, however I'm also not seeing it on the Apple-TV's Netflix and Amazon Prime Video apps - purely Apple Dolby Vision content purchased on iTunes. Perhaps an authoring error on Apple's end leading to incorrect tone mapping on certain TVs?

I’m also experiencing this on my 2018 Vizio P Series(P65-F1). Also agree it is happening in dark scenes for the most part. Mostly on For all Mankind and Apple TV+ shows. Have not seen this on Netflix watching DV content.

I have the same problem. There's no problem with other Dolby Vision content on Netflix, Vudu or MoviesAnywhere app. Also use 4K Blu-ray using an Oppo 203 and no problems with Dolby Vision content. Only from the Movies or TV/TV+ App on the Apple TV, so it can't be the cable or the TV.

As a follow through, if I use the TV app from the IPhone or IPad and forward it using Airplay to the AppleTV, I have no problems so that's what I am doing now. That's why I am doubly sure it's not the cable or TV since it still has to go through the cable after forwarding from IPad or IPhone.
