You can use the settings manager to load an icc profile as follows:
Goto Settings->Devices->Color
Choose your monitor (e.g. Laptop screen)
At the bottom of the panel, choose 'Add profile' to load an existing profile or import another
You can then select that new profile or another for your display
If you want more functionality, I highly recommend dispcal which is a GUI for the Argyll color management system. It's really fun to use and has a large feature set. For example, not only can you manage and manually adjust your profiles, the system integrates with many colorimeters. The package is dispcalgui, e.g. sudo apt install dispcalgui. There is also the gnome color manager (gcm) but this is harder to use IMHO.
