@tshering: That seems unlikely, given the fact that nickel very specifically blacks out those 11 pixels, and goes to the trouble of special-handling already-processed sleep images to make very sure said 11 top pixels are blacked out, rescaling everything in the process to make sure there's no actual useful content behind the bezel (which, while neat in theory, is annoying in practice, since it potentially rescales an already-dithered image, which is a bad, bad thing. [Yup, I did some extensive testing on the subject, to have pretty sleep covers ;p]).
That, plus the fact that the hidden screenshot feature also uses 11 pixels (although in a broken way, rescaling to 1080x(1440-11) instead of cropping the top 11 pixels off)
