I own a lg oled C9 and the feature improved my picture so I don’t understand why you wouldn’t need it. Unless you had your panel professionally calibrated
I spend hours setting the tv how I like it, and I don’t want Apple TV changing settings it thinks I want

Every TV is different though, even the same exact model, which is why people get independent calibrations. I’m not sure exactly how in depth Apple’s calibration is but at the very least it’s tailored to your specific TV which in theory should be better
It depends on the setting. The broader Rtings settings like brightness and contrast will generally get you close to the optimal value, if not right on. Other more granular settings like white balance are best left to professional calibrators. The accuracy of Apple’s implementation of calibration is absolutely an open question at the moment. What’s the target it aims for for? Does it increase contrast and saturation to give you a “better”, ie less accurate picture? I for one an skeptical, but will keep an open mind. I’m sure A/V enthusiasts will be reporting results relatively soon.

You can accept or reject the new settings, so there’s nothing to lose.
But unless you have some objective way to measure what it’s doing, you don’t really know if it’s actually improved anything.

Nice, thought this was for the upcoming Apple TV.

I watched a lot of YouTube videos, other tutorials to fine tune my LG TV (Fios has a far different calibration compared to FireTV 4k, AppleTV, PS4, etc) I'll play with this setting and see what it does.
 
It's an intriguing process, but calibration should be done to the monitor (TV), not the source (AppleTV, disc player, etc).
If the settings on the TV are "close" and this is used to augment that, I can see some value to some folks.
However, if the settings on the TV are drastically off-base (examples: brightness too low, colour set too high, sharpness and noise reduction settings), no amount of source correction is going to make it more correct. The TV will be forever limited to whatever it's own controls have done to the picture.

My experience with well calibrated TVs is if you showed the average person the TV before and after, they might prefer the before.

It takes watching detailed content in a light controlled space to appreciate the correct setting, and spending a little time watching the correct settings will train your brain to like yellows that are actually yellow (not orange), reds that aren’t oversaturated, edge details that aren’t artificially enhanced, and whites that aren’t blooming.

I agree, but I like the idea of the device that’s sending out my content doing the calibrating at least in theory. I have an LG OLED that I’ve calibrated somewhat meticulously but not using professional tools. I have an  TV, a fire tv cube, a Xiaomi android box, a PS5, and the built in web OS all hooked up to it and they all have separate video processing that looks different even for the same streaming content from the same providers. So calibrating the TV itself helps but you also have to look at what’s being fed to it and if my streaming box can calibrate everything it’s sending on top of what I’ve already calibrated the tv for and taking that into account, then that could really be helpful

That’s why you need something objective to judge the picture by. An artificially more saturated picture (to an extent) will probably be more pleasing than one less so, but it’s less accurate by definition.

And yeah, once you get used to a calibrated picture, the hyper-processed settings out of the box look garish by comparison.
 
My A9G has been professionally calibrated. I’m not going to have it tweaked by a phone. Nice gimmick though.
 
the colour is how it should be on it
I have a LG OLED TV also. There are many levels of adjustments built into the software. Unless you have had it adjusted with professional calibration equipment, it is not ‘how it should be’.
I doubt the iPhone will reach the level of pro equipment, but I am willing to give it a chance to see if I, subjectively, think it is an improvement.

Nice.

I am assuming that any iPhone adjustments will be reversible. So why not see what it does?

For the rest of us, who, at best, used calibration software, or adjusted by eye, this seems like a step forward.

Tried here, Dolby Vision when I enabled it under video for my DV capable TV apparently is self-calibrated. It told me it didn't need it.
Ideally. You should turn on “Match Dynamic Range” so that regular content isn’t in Dolby vision and DV content is. Then calibrate using the new feature so that regular content looks correct too.

This is a great feature... but... my AppleTV is connected to a Projector. If I put the iPhone up to the screen, it will block the image I'm trying to have it scan.

Oh I know. I bought my first video essentials DVD in 1998 and never looked back. I could get an amazing picture out of a $99 Orion 13” TV from walmart with the basic PBCHS settings.

Tried this out but it was extremely sensitive to glare or something. It was almost impossible to trigger, and when it did it would never get past more than red or green before resetting.

For me it doesn't trigger at all. Kept it close, far away, lights off/on. Nothing.
