Dolby vision apple tv+

Oh hi, have apple tv 4k box and have had no problems with it u till now.

November 1st saw the launch of apple tv+ which I happily subscribed to. This is where my troubles started.

I've have Netflix and purchased movies through the apple tv app on my iPad and watch them on my apple TV box. All the dolby vision films and tv shows play perfectly not a problem.

How ever on the new apple tv+ it's a different story. During the first episode of The Morning Show when dolby vision is active 3 out 5 scenes have what I can only describe as an old camera film negative look to it! Colours are all inverted in one scene and then the next one all perfect. Is happening in the second episode also and the first episode of See this is also happening. Have changed hdmi cable and input and made sure my LG tv settings for dobly vision are enabled and they are. I turn off match dynamic range to off and there is no video problems but I feel like I'm losing out on the proper 4k quality of dolby vision.

My head is wrecked.

Please i can't be the only one affected with this.

Thanks

Brian
