[UPDATE 20 May 2020]
I managed to solve the problem. See my step-by-step instructions further down in my post.
The Intel HD Graphics Control Panel does not remember my adjustments. Each time I restart my machine, I need to do the following to get my customised color settings back:
1) Open the Intel HD Graphics Control Panel
2) Go to 'Color Settings'
3) Select my custom profile and click 'apply'
[At this point the colours are screwed up big time and way oversaturated. To 'work around' this issue I then do the following.]
4) In Dell PremierColor, I click on any of the profiles, e.g. 'Internet (sRGB)' or 'HD Video (Rec. 709)'. This seems to 'reset' the colours so that the colours actually look like they are supposed to.
What can I do to make the Intel Graphics Panel load my profile. It is the only profile that I created
POSSIBLE BUG in Intel HD Graphics Control Panel
When I close the Intel panel and reopen it, the saturation slider (under Display --> Color controls section) is back at '0' but the colors are shown as if it was on '-14', which is what I set the slider to in my profile. Hence, there probably is a bug in the value read-out for this slider. The slider does not update its position as per the value set the last time the graphics panel was open.

[SOLVED] - Intel HD Graphics Control Panel - does not remember profile - Dell XPS 9560 - Win10 (1909)
What I did:
- Uninstalled Dell PremierColor
- Uninstalled the Intel HD 630 driver in Windows' Device Manager, with the 'deleting the driver' option ticked. [This driver came with the Dell's installer for the Intel HD graphics card.]
- Immediately after step 2, I search for 'Changed hardware' in the Device Manager --> Windows installed a default driver for the Intel 630 device; I did NOT restart the computer although Windows asked me to do so.
- Downloaded and installed Intel's latest driver Intel® Graphics - Windows® 10 DCH Drivers
- With the Intel driver, Intel Graphics Command Center is installed. In there, one can adjust the saturation and color brightness for each color.
Now, my display seems to be reasonably colour accurate. The colours are now much more accurate than ever before using Dell's PremierColor. (And I had spent quite some time with all that.)
NOTE: Before the above, what is important is to first install the Intel 630 driver provided by Dell and Dell PremierColor. Because, if I'm correct, a color profile file named 'CalibratedDisplayProfile-1.icc' comes with one of these two. This profile should be selected in Windows under 'Display Settings' --> 'Color Profile'.
