You should set your ColorMunki to Adaptive High Resolution mode (-H -V), it will be much better. (But may be you will need the next bugfix version of ArgyllCMS as well.) What monitor is this? I think it is a new IPS because it works with 10 bit/color. But the uncalibrated gamma is interesting. Most of the LCD displays follow gamma 2.2 or a flatter curve by default. (It is not a problem at all, I would be happy with 2.35-2.4 for videos. But may be it is a measurement error, or you may want to revisit you OSD settings if your target is lower than 2.35-2.4. May be there is gamma setting.)
