FYI: Prior to posting the picture, I did have all of my variables set to default (besides the fact I am comparing the color tempt of my 4S to my MBP and MB), here's my set up
All were set at Factory default setting in terms of Color (meaning, yes, I know about the Calibration Setting) and that was left untouched. And I know for the 4S, I had no option to do so. If we did, this thread wouldn't even be exist.
All were set at 100% brightness.
AND since I didn't want to drive myself to an APPLE store to compare the different screen tints, I figured I could do the same at home, to see if my warm hue is really that bad.
Like I've said before, I've never really noticed the yellow tinge on my old MB until I placed my 4S next to it. And when I did, I noticed a huge contrast in color.
Did I try to adjust the color of my MB? Yes, but that was after I had posted up my picture. And you know what No matter what I did, the yellow tint on my old MB remain just as yellow. Having my 4S b/w the two made it looked like a perfect color tone (IMO), even though it was warmer compared to my friends' 4S. Now, I am not sure if my MB's sudden yellow screen is the result of infrequent use since I've gotten my MBP, but the yellow did start to fade a bit after I had it on for a few hours.
I am not a computer pro, so I don't know if that's even possible, but maybe my eyes were getting accustomed to the color. But when compared side-by-side, with all three and my 3G, the 4S did show more of a "true" white.
Reason why I posted my picture up was because it's a reference in color. People post that they have a yellow tint to their phone, but really did not share the degree of yellow hue. And even urine color comes in different hues of yellow. And the color tinge on my MB shows a urine color resembling of someone who is extremely dehydrated.
I am trying to help some people out who are obvious very OCD about this issue, and are making themselves see various degrees of yellow when it's not even a major problem. And if it's that bad, then return and wait for the next one to come out.
Honestly, to ALL of us who can afford an iPhone 4S at this time, then we are much better off than many others out there. Consider yourself lucky that you have the money to spend on a "luxury" item.
