Thank you..
I think there are few details that I have been missing.
As per https://wiki.archlinux.org/index.php/ICC_profiles
"Note that the system on which the profile is generated must host the
exact same video card and monitor for which the profile is to be used"
And this contradicts to some extend with
http://www.colorwiki.com/wiki/Cross_Platform_Color
"They will function the same way on any operating system, and can be
easily moved from machine to machine."
I am actually using 2 different machines with 2 very different cards
(one windows and one linux). I think one item that changes the behavior
a lot is the color temperature. I set it manually to 6500K. Windows
would set to this value by default while Linux would try to set to 7600K
by default. On sRGB - windows came at 100% and linux came at 99.9 while
Adobe RGB came at 81% windows vs 79% linux.
There are just a lot of options in Display Cal and even there is
documentation - some areas are lacking detailed explanation for a beginner.
For the record - I am using
Monitor Benq GW2765
calibrator Spyder 5 Pro
Both systems windows and linux are very different in hardware.
I think the 2 are quite a bit closer now.
Thank you all again!

There is actually a warning along the lines of "it should be
OS-independent, but check that the OS and drivers are not doing funny
things behind your back".

In the end, the ICC profile should be independent of the operating
system and only depend on the graphic card + monitor combination.
Hum I would have thought that it is also dependent on the actual
graphic/display driver, no?
If I understand it correctly, the ICC profile is only a mapping of
"RGB values" to "corrected RGB values that, when feed into the driver,
produce the intended color when translated to monitor light
intensities". In that sense, it's true that the driver may change
something.
However, I would expect that the part of the driver that does the RGB
-> light intensity translation is so low level that it SHOULD be
independent of the operating system, specially if you use the
proprietary drivers on both systems. Sadly I currently don't have my
color profiler at hand to test this.
