First, again, as i've explained several times, the plugin do only XYZ/RGBLinear conversion, but the HDR to SDR part is not realy properly implemented, there is only a simple quick linear scaling which may produce results on some case, but that's all.
If you want try something like this :

Code:

Coeff=20.0
ConvertYUVtoXYZ(Color=0,OutputMode=1)
ConvertXYZ_HDRtoSDR(Coeff_X=Coeff,Coeff_Y=Coeff,Coeff_Z=Coeff)
ConvertXYZtoYUV()

Your mediainfo information doesn't provide the chromaticity parameters metadata, so the script assume default for BT.2100.
Try different values of Coeff.
But again, for now, the HDR to SDR part is not realy implemented.
