Where is the Display Calibration mode?!

I don't know...

Here is the other discussion if you are interested - https://forums.macrumors.com/threads/cant-calibrate-new-xdr-macbook-pro-display-missing-color-button-calibration-option.2319627/

After starting the calibrator and calibrating it creates an icc file on the same place as usual (/Library/ColorSync/Profiles/Displays) and fortunately uses it, but if you try the drop down menu or something - you lose the calibration - the file is there, but the mac is not using it... and no way to choose it, so basically the only option is to calibrate and hold your breath... until something happens, which... is kind of ridiculous.

Hope apple will fix it...

EDIT

I got it - it's on the link I posted but I did't pay enough attention - after creating the icc file you can choose it form /Utilities/ColorSync app - Devices - Current Profile:

Right... but sad what macOS is becoming..

Resume for the next poor one who will try to calibrate the monitor:

1. If the 'option and +' is not opening the Calibration expert mode, you need to manually start it, again pressing 'option' and starting the Display Calibrator.app, found in /Macintosh HD/System/Library/ColorSync/Calibrators.
2. When losing the current profile or re-install the macOS, copy the icc profile in the Display/Profiles folder and choose it from Launchpad - Other - ColorSync Utility, than Devices - Display/ColorLCD - Current Profile.

Life made easy...............................

Yes, no matter what I press it opens only this:

'how can I copy ready profile that's created?' means, that I used to keep my profiles, after the calibration, and re-use them on every re-install of the macOS... up to now..

I found a way to start the 'deeeeeeply hidden' (?????) calibration tool, there is a discussion in the macrumors site, but now it appears impossible to copy the icc file and select it from the drop down menu... another ridiculous thing from apple...

btw this new macOS keeps kind of stucking and looks really not good at all

Thanks for the effort!

Strange there are so huge differences depending on the type of a computer...

I know where to find the icc file - but it is not appearing in the drop down menu - no matter where I copy it

Not working on mine...

Indeed - they hide 'the expert mode' too... but that way you describe isn't opening expert mode here...

Also how can I copy ready profile that's created?
