YCbCr

YCbCr represents video using one brightness-related component, called luma, and two color-difference components. You may see it written Y′CbCr to distinguish nonlinear luma from physical luminance. Apple’s Y′CbCr technical note

BetterDisplay lists YCbCr choices when macOS exposes them for a connected display. The name alone does not mean that color detail has been reduced. The chroma subsampling variant tells you whether color samples are reduced.

Read the properties together. YCbCr encoding, bit depth, color range and HDR describe different aspects of a mode rather than interchangeable quality levels.

See Color Mode for selecting among the available combinations.
