No needs to set the colorimetry parameters if it's for setting the same value that are in the according rec.
As you can see, "silly" provide the same result than dither.
It means that dither is only doing a matrix convertion, and doesn't change the colorimetry parameters.
As they, in final, do only simple matrix convertion, these 3 should produce the same result (pinterf added rec2020 recently) :
"silly"
Code:
ConvertToRGB(matrix="Rec2020")
ConvertToYV12(matrix="Rec709")
Code:
ConvertYUVToLinearRGB(Color=1)
ConvertLinearRGBToYUV()
I don't know dither_tools, but it seems it's doing only matrix convertion. Going through XYZ is doing also Colorimetry convertion.
I don't see any issue or surprise with these results.
What is exactly your issue ?
If it's difference between dither and ConvertXYZ, it's expected, as dither is only doing matrix convertion.
