Oh why thank you , I had a great laugh .
Calibrating a display , requires a source of reference .
In this case where is he getting the reference ?
These are just generic settings , so common that every TV channel is providing them nowadays . That is not called calibrating .
Also the fact that you need to tell people to turn " Dynamic tone mapping " off in Dolby Vision

We always use 2.4 for SDR , because that is the most reliable way for 1D and 3D LUT to generate consistent color gradation across all luminance range .
Effect is more obvious in the recent TV because of added precision point from 3D LUT in 2018 / 19 / 20 / 21 OLED models . [ The A , B series are excluded . ]
People tend to raise it to 2.2 doesn't mean it is optimal , it is just that our vision become progressively weaker at picking out errors and mismatch in a brighter room , thus interference from ambient lights .
Gamers also like to do that because they want to see more in darker side in competitive scenes .
As for the color balance , You don't need to follow his settings as long as you have a working Ipad , or a Nintendo Switch ( surprise ) .
Play a full screen white pattern on the youtube app , get the full screen white on your TV to look as close as possible.
From my experience , these little gadgets are extremely accurate in colors which came as a surprise to me .
Back in the days , when we didn't have all these tablets and didn't have any tools , we were resorted to using a piece of A4 Paper .
Again , don't call that calibrating . That is just trying to make the screen as accurate as possible according to the limits of your eye sight .
but who said anything about calibration.
ozak said he was looking at some TV presets over YT.
So the "Reference" was referring to sources of TV presets.
And I already said Quantum TV is not legit.
