I agree, considering Rec.2020 was only standardized by the IEEE on August 23, 2012. It uses a much wider gamut (i doubt many displays today can actually cover it), and 10-bit or 12-bit per channel.I doubt the very first 4K Blu's will be Rec.2020 compliant anyway, probably mastered to Rec.709 with 8-bit color depth.
Gamma is always a moving target. Some even find 2.2 too dark for their likings for certain films. Since most out of the box consumer TV's measures around 2.0, maybe studios are mastering on a low gamma so it looks better for the masses? Even worse, low budget material maybe mastered on uncalibrated monitors with low gamma!
The standards body should really define what is considered meeting the standard and what is not. Similar to car saftey ratings. E.g 5 star could be DE < 1 for primary/secondary/greyscale tracking. Otherwise, marketing will just run wild and calm everything is accurate and calibrated.
Win7 includes a LUT loader, you don't need colormunki software. However it is disabled by default.
Instead of me describing the steps, I think these screenshots will help you more.
The ASUS 27" claims pre-calibration as well.
The funny thing with the Samsung is that, Samsung is the master of oversaturation, just look at their Galaxy S2 and S3 phones
Do you mean loading the LUT which adjusts gamma from the ICC/ICM file? This normally changes how your desktop "look". The ICC/ICM file when only associated with the display are used for color correction with supported applications.
