DolbyVisionColor

data class DolbyVisionColor(val dmMetadataId: Int, val sceneRefresh: Int, val yccToRgbMatrix: List<Rational>, val yccToRgbOffset: List<Rational>, val rgbToLmsMatrix: List<Rational>, val signalEotf: Int, val signalEotfParam0: Int, val signalEotfParam1: Int, val signalEotfParam2: Long, val signalBitDepth: Int, val signalColorSpace: Int, val signalChromaFormat: Int, val signalFullRange: Int, val sourceMinPq: Int, val sourceMaxPq: Int, val sourceDiagonal: Int)

The colour of the reshaped signal, FFmpeg's AVDOVIColorMetadata, which FFmpeg fills with its defaults when the RPU carries none of its own.

A composition takes yccToRgbOffset off the reshaped components and turns them into L'M'S' with yccToRgbMatrix, makes them linear with the PQ curve, and applies rgbToLmsMatrix. Each matrix is nine entries, row by row.
