Are there any success stories for fixing stuck/dead pixels, or should I just learn to live with it?

I have a single, tiny green pixel on my upper screen. In practice it's not that big of a deal, but I really just hate to see this on a brand new device that cost me nearly half a grand. I'm trying the pixel unsticker videos right now, but before I sink too much time and effort into this, I just wanted to know if anybody has been able to fix these, or if they're pretty much permanent?
