1 month post op of Kors Whitening, I have uneven teeth color and mixed results. Will the colors even out? (photo)

I have done a month of the Kors whitening system at home and I have had 2 in office whitening procedures. My teeth are lighter but not dramatically (b1or b2 before procedure). My problem is that my teeth have white lines running through them and are not near as white at the top of the teeth. They are white at the ends and then darker at the gums. I haven't bleached for 5 nights. Will they even out? Why did this occur? This system was $1800 and I expected it to work better. :(
