This engineer is making some guesses but they are pretty reasonably based and may help people better understand what is being delivered with "nano IPS".
I will also note that most wide gamut displays have a far better green and red wavelength response than ordinary White LED or White CCFL backlights. You will notice a better variety of red shades as well as much more proper greens (with varieties) and aqua colors which an ordinary backlight simply cannot provide. Once your eyes notice it, you may find it difficult to go back to simple white backlights and srgb screens.
