This is a head to head Windows Phone 7 LCD vs Super AMOLED devices on LG Optimus 7 and Samsung Omnia 7. Besides the advantages of Super AMOLED (like contrast, deep blacks and luminosity) there is also a downside when displaying color gradients. Samsung Omnia 7 seems to exhibit color bleeding when compared to the same image on the LG Optimus 7 mainly because Super AMOLED use PenTile display technology with RGBG (Red-Green-Blue-Green) and, while Samsung Omnia 7 Super AMOLED should be 24bit in color depth, CIsForCoder reports that it is indeed 16bit and warns developers to avoid images with gradients in their application since those might look good on some devices and bad on others.
