Another way to get them, it's if you're using DGIndexNV, on HEVC HDR stream.
In that case, you'll have in the DGI file this line (for exemple) :

The values are the following:
MASTERING GreenX GreenY BlueX BlueY RedX RedY WhiteX WhiteY MaxMasteringLevel MinMasteringLevel
The GreenX GreenY BlueX BlueY RedX RedY WhiteX WhiteY are by 0.00002 steps.
The MaxMasteringLevel MinMasteringLevel are by 0.0001 steps.
In our exemple, it will result :
