But what is the point when it just take few clicks to generate any LUT in LUTCalc. It is free online tool https://cameramanben.github.io/LUTCalc/L...index.html

FranceBB's LUTs are created in same LUTCalc tool as well.

By the way, both LUTs produce different transformation "look". So i guess there is no single "universal" transformation math from SDR to HDR and it is all more-less subjective or based on some different math for some different purposes.
