The Care Team speaks for Microsoft. Probably cannot use what they say in court, I agree, but what else do you want, Satya Nadella to tell you directly?
I've been through at least 10 support representatives, the Microsoft Store and the Care Team (which is as high as you can go for support).
Not only that, I checked at least 20 units in different stores, in different locations and they ALL had it.
Given my experience and what the Care Team told me, it's far more plausible to assume that you can't see a light version of the problem, then believing I'm just that unlucky
You might be right, but statistically speaking I have to go with the first.
