do you think itll ever get sorted? the thing that concerns me is those who have very minor yellowing, as its a visual thing how can it ever be proved?
i think mine may have minor yellowing towards the bottom, 3 people in my house cant see it. 1 can....me! i wish there was some form of diagnostic you could run... i know you cant but im sure if id never read this thread then id never have noticed it..... now i have what do i do??? machine seems ok apart from this.
If the yellow tinge is there on your iMac, and on others it is not, then I would regard this as a "fault" that can be proved - surely the proof is in the pudding, it is visible to your eyes and others. Your argument to Apple is that you are unable to correctly colour correct images or use Apples's colour grading tool "Colour" with the screen being evidently unable to correctly display true whites.
