Description
Loss of detail in low levels is the adverse effect in which the image luminance levels are "crushed" to black, causing dark portions of image to solidify in value.

Image quality is degraded by the loss of detail, negatively impacting the customer experience and technical soundness of the programme, although sometimes creative intent.
Definition
Used in Checks, the system shall review content for low level detail loss. Optionally, the system may report timecodes of where the detail loss appears.
