Color calibration issue on High Sierra

Just upgraded to High Sierra, and now my iMac screen lost the tone, brightness and colors I used to. The colors are pale, the tone is cold, the white is blue-ish... It looks disgusting. 

I can see that the default profile for the display was overwritten during the installation: it says now iMac-2838C3DD-A394-78C1-4A5E-57649BBC5643.icc with the today's date.

I suspect that I should be able to get back to what I have if I am able to get my previous display profile somehow (which was a factory default, actually). Can I get somewhere the factory default display profile for iMac 21.5-inch, Late 2013?

Or is there a way to restore my MacOS Sierra installation?

Yes you can restore back to Sierra however only if you have a backup of it. How you would do that is by using your bootable clone to restore or you can use Time Machine to restore. If you have a SSD installed as your primary drive in your computer then all bets are off as the file format is different on HS than it was on all different versions of Mac OS.

Comments like yours ALWAYS come up when a new release comes out. My advice is be patient and wait for some updates, there is a chance what you are seeing is your perception even possibly imagined.

Same on my iMac (27-inch, Late 2012).
Switching off 'Automatically adjust brightness' in the Displays System Settings did the trick for me.
The transition between the two states is subtle so close your eyes and wait a second or two.
