color spaces – How to "read" the DisplayCAL-profile-info correctly or is my LCD calibrator defective?

It will probably be a stupid question I want to ask, but I will still try – do not throw stones at me.

I am neither a photographer nor a graphic designer, but color reproduction is always important to me. So I bought a former Spyder3Express calibrator and I used it on my (also very old) ThinkPad W530 with B156HW01 V4 screen (announced at 95% AdobeRGB and 98% sRGB).

Until now, I used the Spyder3Express utility for calibration, but I recently switched to DisplayCAL (the calibration takes longer to complete but gives better results – IMHO) and just for fun, I've used this DisplayCAL-profile-info application to display information about the profile created by the application, and I'm not sure to look at the figure / graph correctly (showing the cover color spaces). Let's look at the following picture:

Now, I've seen a lot of similar images on the website where, when they test a laptop, they also calibrate the screen to check its performance, adding numbers. resulting comparison on the revision web page. But the models reviewed here almost never go beyond the comparison model (well, in case the LCD is not so good – of course, if we look at a professional graphic workstation, then it can / does). For example, this is Lenovo ThinkPad P1 (Xeon E-2176M, Quadro P2000 Max-Q) reviewed by, classifying the screen as 100% sRGB (Argyll 3D) and 87.6% AdobeRGB 1998 ( Argyll 3D):

Looking at both images, I'm not sure if the calibration of my LCD screen with my Spyder3Express calibrator was faulty (maybe I should get newer hardware?) Or if I had the chance to get a very good screen B156HW01 V4. Also based on the low profile information (from my ICM profile) where the GAMUT_coverage information is listed, I can see the following:

    GAMUT_coverage (dci-p3) 0.9867
GAMUT_coverage (srgb) 0.9962
GAMUT_coverage (adobe-rgb) 0.9962

According to the specifications of the LCD model, the coverage of AdobeRGB should be 95% and 98% sRGB, but mine says 99.62% for both; does this mean that I have a screen (almost) 100% AdobeRGB / sRGB? , or is my calibrator really bad? Looking at the figure, I see that greens, yellows and reds are very much bigger.

Needless to say, I am generally very satisfied with the machine / LCD screen, the colors are beautiful, although the red is so bright / bright that it burns my eyes, making the red of my monitor external resembles that of the orange.

In addition, I tried to calibrate my EW2440L Benq 24 "external monitor and a smaller ThinkPad X240 with an LP125WF2-SPB2 IPS display (74% sRGB) .I am very pleased with the results.
