Thank you All!
I was not aware of the article. It is very informative indeed.
@Guillermo - if you create such sane options that you use - it would be
very beneficial too.
I can see there is quite a bit to learn in this area... admittedly I
have been doing a few things the wrong way.

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.
Yes, I think the colorwiki link was referring mainly to printers, is a
bit misleading (my bad to include it here). Is the same discussion as
with the driver: in principle the graphic card should not affect the
colors that are sent to the monitor, but graphic cards can be so
different between them that in practice it does matter. Same
generation of the same vendor may be OK, two completely different GPU
is probably not safe.
And yes, color temperature is very important: the profile tries to
match the color temperature you ask for, so a profile with a target of
7600K will look a lot bluer than one with a target of 6500K. You
probably want 6500K, as that is the standard for monitor viewing.
Brightness is also important, to a lesser degree.
There are just a lot of options in Display Cal and even there is
documentation - some areas are lacking detailed explanation for a beginner.
Yeah, it also took me a while to understand which options to use, and
even after deciding I was second guessing my configuration all the
time. I'll post tonight the options that I found the most "sane",
maybe it's helpful for you as a start point. If I find the time I'll
try to also write a small walk-through of what I did when I calibrated
my monitor (including the color temperature options).

Guillermo
