Last week, we noted that some Retina iPad mini displays were exhibiting image retention issues, while in general other users were expressing some dissatisfaction with the color gamut of the Retina iPad mini's display, particularly compared to that of the iPad Air. In an extensive review of the Retina iPad mini, AnandTech came away extremely impressed with the device but cited that color gamut issue as a significant disappointment.Although display resolution is no longer a concern on the mini, color gamut hasn’t changed between the old and new minis.
