Since we're getting into this a bit deeper...here are two Apple documents related to "pixel anomalies" (document differences based on the date of the product):

About LCD display pixel anomalies for Apple products released before 2010
About LCD display pixel anomalies for Apple products released in 2010 and later

Unfortunately these documents don't spell out what the exact "dead pixel policy" is. Some companies actually say how many:

- total number of dead pixels on a display that are acceptable
- number of dead pixels that are clustered in a specific area (how tightly clustered in a specific area)
- number of dead pixels that are actually adjacent to each other

Here are two older articles from "engadget" and "appleinsider" that claim to have come across an Apple internal document/chart that better spells out the "pixel policy" for display panel replacement (at least at the time of the article):

Apple's dead pixel policy leaks out, up to 15 anomalies 'acceptable' on 22-inch and above screens?
Leaked Apple dead pixel policy allows two for iPad, none for iPhone

Unfortunately this document seems to be before "retina" displays...to get an idea of of what the dead pixel tolerances would be for them.

Just came across this as well (an older "dead pixel article" from 2005)...spelling out the pixel policy by manufacturer for notebooks (of course Apple is "unstated"):
