A per-device calibration transform matrix that maps from the reference sensor colorspace to the actual device sensor colorspace.
This matrix is used to correct for per-device variations in the sensor colorspace, and is used for processing raw buffer data.
The matrix is expressed as a 3x3 matrix in row-major-order, and contains a per-device calibration transform that maps colors from reference sensor color space (i.e. the "golden module" colorspace) into this camera device's native sensor color space under the first reference illuminant (CameraCharacteristics.SensorReferenceIlluminant1).
Optional - This value may be null on some devices.
