Urge Notebookcheck to show up the Color Gamut in both the sRGB and AdobeRGB

Urge Notebookcheck ought to show up the Color Gamut in both the sRGB and AdobeRGB (with the measured graph, not only numeric value), in factual market that sRGB is much more important and widely, looks at outside of a few special needs.

And, the latest 10 years, even the professional printing equipments are not necessarily that all use the AdobeRGB CMS, such as many of the minilab laser photo printing system are with sRGB CMS (Fujifilm and Noritsu), though these device hardwares might support AdobeRGB, the equipment cost is tens of thousands of USD or is even several hundred-thousand USD.

Also, particular it should be noted for an AdobeRGB monitor is required to handle in correct CMS way, and including with your all of the software are needed with CMS (color management system), otherwise, it could cause to display up unsuitable color.
This typical example, some hobbyists prefer AdobeRGB very blind, unthinkingly used the AdobeRGB color-space to their post-processing images, meantime, it lacks correct CMS way giving to their all of software, or even a monitor is not with AdobeRGB matchable. And then they play back image in an image viewer even a web browser, some who exclaim that looking, the color is so bad, sRGB is so bad! Really too funny.

A lot of software are just suitable for sRGB,  even many of the image viewer do not support CMS, which just a part of the image viewer can be supportable of CMS, like ExifPro.
A lot of hardware actually in itself is along a Color Gamut even smaller than sRGB range, despite the firmware or included with an optional AdobeRGB mode, like some cameras, phonecam, scanner, printer, etc....

The vast majority of the general users do not know what to properly handle the CMS, therefore the AdobeRGB Color Gamut monitor to be fully meaningless for them, even likely worse, just causes them to waste more money!

What is a true different point between an sRGB-screen and an AdobeRGB-screen, exactly how degree to be viewable? 
If both screens are equally fine, merely the Color Gamut is different in both of them, for one is sRGB 99% and the other is AdobeRGB 99%, in both got equally a well calibration out the factory, like this, that you are impossible easy to see notable differences appearing in main color zones on both of them.
The differences existed in the outermost zone of AdobeRGB just, only in extreme Green or extreme Cyan zones. See fig here:
http://en.wikipedia.org/wiki/Color_space#/media/File:CIE1931xy_gamut_comparison.svg

In fact, under most cases people easily seen of obvious color differences the true causation is not because the sRGB Color Gamut, but a worse screen configured in many notebooks. Which are like these, extremely poor display panel, extremely bad display calibration out the factory, this Color Gamut is much smaller than sRGB range (even almost 50% of sRGB),  too bad of the anti-glare capability, a much worse of brightness and contrast range, a much worse of max viewable angle, etc, etc....
In some notebooks, the displayed color of screens are unable to be calibrated properly done, the hardware were congenital deficient capability, which included like partly non-cheap Thinkpad models.

When the CMS had not been used, the system to work equivalent to sRGB mode in default, whether it be MacBook or Windows.
And, most of the laptop and notebook that a screen is Color Gamut lesser than sRGB. In most cases it do not need with AdobeRGB, but the Color Gamut is in sRGB 99% to be better, which very needed.
(In 2012, MacBook Pro with Retina Display that the Color Gamut is merely the 67.3 percent of AdobeRGB, thus the screen is not suitable for working in the AdobeRGB space, more suitable for sRGB. In 2013, the 13" MacBook Air covers merely 67% of sRGB or 51% of Adobe RGB.)

Please notice, not what AdobeRGB Color Gamut is certain to be a good screen, there are ever some of the TN screen notebooks that is even a wider Color Gamut than a low-end IPS screen, but is still a bad visual sensation.

sRGB 99%, Visual Angle wider than 170-degree (in 170-degree that contrast higher is better).  From the whole of brightness-range, each brightness-level (not in an average value) to have following performances, Accurate gray-scale Gamma (each level from 10% to 100% of brightness), Accurate color (each level from 10% to 100% of brightness), Accurate color temperature (each level from 10% to 100% of brightness), and all the true specs of sorts are also good capabilities, would be good enough,  just excluding for purpose of AdobeRGB color.

Possibly the sRGB mode goes against to your photo quality?
No! If your photos go to printing published, send photos to a professional printing studio, the pre-press that they able to convert your photo into AdobeRGB, once it is needed. Which is no going against the photo quality.
Finally, more important to convert the color space to CMYK and will match their printing ink system, and not about the AdobeRGB. For the factual printing system is some AdobeRGB color incapable of being coated, like extreme Green or extreme Cyan.
