Comment (by Balling):

 chroma-derived-nc is just a matrix that depends on primaries and white
 point. Every combination of primaries and white point leads to special
 matrix, like how CIE D65 + BT.709 is BT.709 matrix or Illuminant C +
 BT.470 primaries make BT.601 matrix.

 Nc means it is using NC, non constant transfer function. There is also CL,
 where transfer works differently, like in BT.2020CL.
