Mine is (as far as I can tell, comparing it to my iPad and MBP) absolutely fine. No screen "interlacing", no yellow tint. I did have an odd camera bug today where it would appear to take the photos but not save them to the camera roll: cured by a reboot, I guess it's an iOS7 bug that will get fixed (I've reported it to Apple). Otherwise no issues (apart from the gyro, but I'm not really counting that as a problem at this point as it's so widespread and very likely to get fixed).
glad to hear you got a good screen, mine is defiantly yellow tinted, especially noticeable when reading Mac Rumours
