Using black-point compensation

The Use Black Point Compensation option controls whether to adjust for differences in black points when converting colors between color spaces. When this option is enabled, the full dynamic range of the source space is mapped into the full dynamic range of the destination space. When disabled, the dynamic range of the source space is simulated in the destination space; although this mode can result in blocked or gray shadows, it can be useful when the black point of the source space is lower than that of the destination space.

The Use Black Point Compensation option is selected for all predefined color management configurations. It is highly recommended that you keep this option selected.
