Yeah the "super" bit is more to do with the internal layout of the display and doesn't in itself help with the problem of LEDs wearing out
I suppose it's too early to tell yet if the materials this particular screen is made from is going to help with screen life - we can hope
What will make the most difference is the brightness of the screen, if you can accept keeping the screen dimmer then the individual LED pixels will last longer and "screen burn" will take longer to become noticeable.
Edit: Forgot to say that although Samsung is using an adaptive drive technology which compensates for LED wear, it doesn't prevent wear.
So at some point "screen burn" will happen, it's just how long it takes.
How long do you plan to have your phone?
