+description:
+  Tone Curve Conversion (TCC) is one of Media Profile Path 3 (MDP3) components.
+  It is used to handle the tone mapping of various gamma curves in order to
+  achieve HDR10 effects. This helps adapt the content to the color and
+  brightness range that standard display devices typically support.
