Dolby Vision Flicker with Apple TV 4K

Having an issue whenever I output my Apple TV 4K in Dolby Vision 4K 60hz or 50hz- I get a very quick flicker (almost like a second image of the screen superimposed over the main image, but slightly shifted and discolered).

It it happens very quickly once every 30 seconds or so and is most noticeable on the main menu screen (but also happens during video playback). It only happens in Dolby Vision output. 4K HDR and 4K SDR are fine.

Im running on an LG OLED55E7P. I’ve tried multiple HDMI ports on the TV and multiple HDMI cables. Also running the latest LG software (4.70.07). Haven’t been able to figure out a solve.

Here is a video of the issue (most noticeable if you look at the Apple Music icon on the screen): https://youtu.be/ORGrnFdHnCs

I am also having this exact same problem when connected to an LG OLED65C7P. Hoping it'll be fixed with a software update :/

Swapped out my Rocketfish ultra hdr HDMI cables for the Belkin ones at the Apple Store and the issue persists. Hopefully a software update will fox this issue.

Afraid I’m not seeing any change. I had my ATV replaced this week. Watching Dark on Netflix and still seeing that judder. Just came across the proposed solution above will give it a try.

Do you mean flicker because judder is a different issue that is dependent on source content and framerate of TV.

I have the same thing on my M series. It’s not just LG.
