Do bear in mind when you throw up a black screen on the native contrast on the Nano Cell panels is lower than a typical IPS. Most IPS screens you see online can vary from 900-1200:! while the Nano Cells are typically 700-780:1 so things do look a little worse. All IPS greens will have glow, the pixel behaviour lets back light through and cameras do make it worse, even in the two here you can tell it's overexposure. I did measure a GL83A at just under 900:1 but most of the 850's I've seen have been worse and this is mainly down to the poor black output.
