And if you mentioned the small white patch on a black screen: This H-IPS display has a very bluish black when I see it next to the S-PVA display. So, may be it's not a good idea for me. And I think it's not my eye, the Colormunki also says that my black point is bluish, and I loose a lot of contrast when I tell 'dispcal' to correct it as well. This is not a real problem in real life situations when I have some colors on the screen. It looks "black enough" (when I try to keep the contrast ratio with dispcal).
