Testing color management isn't hard, and we even supply some test profiles.

# Как проверить, правильно ли работает управление цветом?

The effects of a color profile are sometimes subtle and it may be hard to see if anything much has changed.

In GNOME we ship several profiles for testing that make it very clear when the profiles are being applied:

Bluish Test: This will turn the screen blue and tests if the calibration curves are being sent to the display

ADOBEGAMMA-test: This will turn the screen pink and tests different features of a screen profile

FakeBRG: This will not change the screen, but will swap around the RGB channels to become BGR. This will make all the colors gradients look mostly correct, and there won't be much difference on the whole screen, but images will look very different in applications that support color management.

Add one of the test profiles to your display device using the System Settings Color preferences.

Using these profiles you can clearly see when an application supports color management.
