The amount of change to your image depends on the color accuracy of your camera’s sensor and color neutrality of a particular lens. It also depends on the profile Mode (Saturation, Colorimetric, or Portrait). To see the results of the calibration, look at the HSL panel in Lightroom or Camera Raw or the Color Correction panel in Phocus. Adjustments will be made to each of the Hue, Saturation and Luminance controls for each color channel of the image.
