You are exactly correct. These are stuck pixels, not dead pixels. Not that there's huge difference. Dead means it won't come on, stuck means it won't shut off.

One method is some very careful display hacking to force the stuck pixels to turn off and stay off. Essentially turning a stuck pixel into a dead pixel with is generally less of a problem.
The other method (which has several variations) has to do with physically poking, prodding, etc on your screen with the hope of shifting the materials of the display and unsticking the pixel. It 'can' work if you do it right, but you run a high risk of destroying your display. Also, there's absolutely no way to do it on the Pre because there's a touch surface between you and the actual screen.
That's actually very normal. White screens always show dead pixels because a dead pixel is always out, and white means all the pixels are on full power.

I'm sure that if the OP looked at a black full screen image, he'd be able to see it. You can tell whether the stuck pixel is a red, green or blue pixel, or a cluster of pixels based on the color it appears as on a black screen. i.e. a stuck pixel that shows green is just the green pixel, purple means it's the red and blue pixels of a triplet that are stuck, a white spot means that an entire pixel triplet is stuck.
For anything between black and white, whether or not you can see a stuck pixel depends on whether it is a red, green or blue pixel that's stuck, and how bright that particular pixel 'should' be for the color being displayed.
