So it is actually the ATV4K displaying dolby vision pop up on the screen.
that's incorrect,
100% confidence, no questions, without a doubt the TV is making the popup
The aTV
is making a change in the signal that causes it, but the decision to display it and the actual image comes from the television.
I've also changed TVs and the logo looks different.
I've not seen a set that will allow you to turn it off.
if you have the format set to 4K Dolby vision as the default video output, you can turn off match frame rate and dynamic range. Once you do that you will still be able to enjoy dolby vision content WITHOUT that annoying ass pop up. Hope this helps
you don't want to set it up like that. content that was not created in dolby vision will be up-converted. It will cause your image to look bright and colorful, but it won't necessarily make it better.
For movies released in dolby vision, there are very talented people that are paid lots of money to make sure everything looks correct on a frame by frame basis. Those people also are starting with a very high quality image so they have lots of image information to work with.
the way you have it set up, any SDR image will be unconverted in the aTV to HDR. It starts out with a lower quality image and the software in the aTV has to make up information that doesn't exist, This is handled by an algorithm, meaning there's no art to what's happening, and in a lot of situations it can actually make the image worse.
You're saving yourself 3 seconds of a badge in the corner of your screen (and probably a short blackout on the TV), but sacrificing image quality on the entire duration of every non-HDR thing you watch.
I wish Apple TV+ would display technical info on the same pop up that displays film/TV rating. Or add "Technical" on the chapters/subtitles/audio slider.
I realize most people don't care, but home theater enthusiasts would love it.
You can enable the developer tools, and add a video playback overlay that has a lot of that info. The overlay enable/disable is about 3 layers deep in the main settings app, so it's not a quick change.
to do that you need a free apple developer account, and Xcode on a computer on your network. there are guides online if you search for "appleTV developer HUD" One note, Xcode is around 30GB to download and you need another 30-40GB free after you've downloaded to install it.
