You, hopefully, thought you had a problem by looking at it (rather than rampant paranoia and OCD behavior). You tested it.
That is NOT the OP's situation. He has no reason to believe he has a problem other than the complaints of the people here. If he was fine and unhindered before, all you've done by encouraging this nonsense is created a problem.
My discouragement of casual users from getting their panties I'm a was in no way "hinders" your work. It might hinder your alarmist crusade, but I can live with that.
Wrong; the OP can clearly see that his Mac's display is yellow by comparing it to the iPhone. This was done without any input from me. I'm proposing a way to confirm if the perceived yellowing is real or not. If he didn't have a reason to believe he had a problem then he would never had started this thread. He started this thread because he believed he had a problem.
