This same issue that 0.00001% of users of every apple device ever have?
Completely disagree. My parents would never have known that their first ever Apple product, a 2013 21" iMac was not meant to have such a yellow-tinted screen, muddy yellow/green where blues should be and yellow where light greys should be.
It took me to point it out to them.
The iMac was returned and the new iMac screen was fine.
Apple obviously has bad quality control and I think that the majority of defective screens are not noticed as such by most consumers.
I certainly noticed and found it very apparent. When you work a lot with photo's you notice these things.
Bad quality control and defective screens are bad whether the end user notices the defect or not and whether Apple fanboys refuse to accept it or not.
Apple is on a mission to make cheaper products to make more profits for themselves, at the expense of material quality, as can be seen with this retina iPad mini, the iMac screens and the plastic iPhone 5c's-with-very-little-price-drop-passed-on-to-the-consumer.
Apple recently seem to be manufacturing cheaper quality products whilst keeping their same high consumer retail price, in an attempt to keep a supposed mark of quality attached to their product.
This is a see-through strategy that I cannot see consumers being fooled with for long.
