I'm telling you, this is simply standard. As I also said, I don't know if Apple has more recently changed their policy, or sourced different screens.

Here's a quote from Asus:

"Since LCD panel is made up of millions of micro electronic pixels, if one pixel no longer functions normally, it will become a bright or dark dot. By ISO 13406-2 standards, ASUS conforms to the acceptance level between 3 to 5 defective bright/dark pixels. In order to deliver ultimate vision experience to ASUS customer, if your panel is less than or equal to the above number of dots, then, it is considered as an acceptable LCD monitor.In addition, the Premium Range of ASUS LCDs offers a unique Zero Bright Dot (ZBD) warranty.Please refer to ASUS LCD Monitor Bright/Dark Dot Warranty Table below."

Your LCD display is possibly subject to replacement if it meets the criteria outlined in Table 1:

[excerpt from Table 1]

Threshold for warranty replacement

Bright = 1 or more [pixels]

Dark = 6 or more [pixels]

And here's an older (2010) article which describes the policies of many manufacturers, including Apple.
