They mentioned a cool feature which is actually an upcoming TVOS feature that will work with older Apple TV4K and HD as well: colour calibration of your tv using your iPhone.
Will definitely try that on my Apple TV HD.
I checked the color calibration on my TV with my i1 Display LT and it was about 99.9% correct. If you have a good TV then this step was done for you and it's unlikely to have drifted noticeably — I checked mine after like 7 years of use. 52" Sharp AQUOS CFL backlit here.
Never worry about theory as long as the machinery does what it's supposed to do.
