Oh give me a break. The display is very damn good. They are just being picky and trying to get something for free.
I completly do not agree with you.
1. Those displays are not all that great, but you should see what you buying before spending 2000+. Another story is that quality varies a lot in between the models and that also schould NOT happen
2. BUT Apple should be fair and do not suggest consumers that these screens are 8 bit. And they should be punisch for that
