ok so i noticed this thread a while ago and had no clue what you guys were talking about until i just replaced my phone and it has it now so i know exactly what your talking about and i also know what it is haha!...ok so the way the screens are designed you have the lcd screen then the touch screen hardware on top of that then a platic "protecive" layer on top of that...the plastic layer is made of a bunch of peices of plastic sealed together and then sealed to the phone...the rainbow effect happens when the layers start to seperate....most commonly from a screen protector being peeled off....my replacement was a 30day exchange an the screen protector was not in the box so im assuming thats how mine got it....but hopefully this helps the rest of you...also if you slide your finger over the smudge it disapears until you relieve the pressure from that particular spot bc you are squishing the layers back together
