So far it looks like Apple has more tricks than treats for us with a hidden screw securing the display.

After dispatching two hidden screws and two exposed screws with our 54 Bit Driver Kit, we are able to lift the LCD.

Pulling up the display reveals a large metal plate, held in with no fewer than 16 screws.

We found similar plates in the iPod Touch 5th Generation, and the iPhone 5, so this seems to be a new iDevice design convention.
