Easy....because some people have different viewing habits than others.
Banding is nothing to do with viewing habits, its a set-up out of the box issue that several people had. The TVs are manufactured in ways that can (and do) cause variations. Burn in is obviously part of this variation - as rtings has showed with their burn-in test that had one set display worse burn-in than another. Including this snippet which shows that there can be a variation in the manufacturing process.
We contacted LG regarding the strange results in week 4. LG engineers visited our lab a few days ago and were able to confirm the 25% window on the Live CNN and FIFA 18 TVs are a result of a factory issue (see our video here). OLED TVs are produced in a hot process, and after cooling a 25% window is shown on each panel. Some TVs which haven't cooled completely can produce invalid results for the lookup table used by the 'Pixel Refresh' function, causing this 25% window to become visible. Only some 55" OLED TVs were affected during part of 2017.
