Apple TV - Calibration?

Don't think it matters. I ran the program on my previously-calibrated TV with lights on and off. Both times, I received a message to say my TV is balanced and no changes are necessary.
That's probably not necessary. "Accuracy" when viewing a display is based in part on your lighting conditions. A totally dark room might give you "ideal" color balance, but what good is that if you don't normally view in a totally dark room?
Since ambient light affects your overall viewing experience, you'd want to setup under typical conditions, rather than "ideal" conditions.
You hold the phone an inch from the TV screen to calibrate, so I'm not sure how much ambient light plays a factor into the calibration, unless you have direct sunlight hitting the TV screen.
Good point but don't lighting conditions change depend on daytime or night time viewing. Ideally there would be a couple of presets for day and night but perhaps that difference isn't so great.
Edit: So I have my Apple TV set to 4K SDR and match range/frame rate. Calibration made a minor difference on my Sony A1E OLED and took a little bit of blue out of the picture.

If your Apple TV is set to Dolby Vision or HDR output as default then I don't think it works. It has to be in 4K SDR. Then set your range and frame rate matching on. That way only content that is mastered in HDR/Dolby Vision is actually presented as such when played. This means your content is played based on its encoding. If your default setting is set to HDR or DV then all content is processed/converted and presented as such regardless whether it is encoded for HDR or DV.

No. You put your iPhone face down on the TV screen. Room lighting can’t affect the results.
It instructs you to hold it “within one inch” of the screen. I assume that’s so people don’t hold it too far. I just put it directly on the screen.
I just tried and it says it's not needed when using Dolby Vision
I run my Apple TV 4K box at 4k SDR with match frame rate enabled and match range enabled.
I ran the colour balance feature with the ATV in 4k SDR.
I understand that colour balance doesn't work with DV enabled because DV has its display profile in the same way that my TV has been loaded with a custom calibration DV profile.
I just have a aTV HD, and my CX says it doesn't need calibration. ISF Expert Bright room profile.
Yes, it's not needed with DV because DV has it's own colour profile which the ATV doesn't change.
Since you are running it with an ATV HD, the colour doesn't need to be changed because your TV's SDR colours are fine and not because your TV supports DV.

Two Apple TV 4K’s and two Vizio 4K sets. 1 calibrated on the first try. The other has failed every time, on the 20th try. I’ve tried it all, even laying it flat on the TV. It still said “hold your phone close”. Can’t get any closer without breaking the TV.
I have 4K SDR set and with warm 2 by default on the CX i tried the calibration and I found it basically made it cooler which I don’t think is entirely correct. I could be wrong
Nope. That is not necessary. I ran it on my Apple TV in the living room in the middle of the day with the shades open.
I have successfully run this process on 5 televisions - three Samsung models (40", 65" and 75"), an older Sony and a Toshiba Regza... four worked perfectly the first time. I had a bit of trouble with the 75" Samsung... but after reading this thread, I placed the phone directly against the tv screen... and it worked perfectly then. The differences were minimal/insignificant on all of the televisions... much ado about nothing, IMO.

Figured out what my “problem” was. The test will not finish if my second TV is in Standard picture mode. Has to be in a different mode. The other TV was in Standard and it worked just fine. They’re both Vizios, one from 2017 and the other 2018.
To me, this works about as well as the ear tip fit test on the AirPod Pros, it’s hit and miss.

Just in case anyone else has a 2017 Vizio E Series, here were my results by picture mode:
Standard - Fail, “Unable to Measure”
Calibrated - Pass
Calibrated Dark - Pass
Vivid - Fail, “Unable to Measure”
Game - Pass
Computer - Pass
The “Computer” picture mode is basically Standard with a higher brightness level.
Good luck everyone. Obviously, YMMV.
