I use rasppbery pi as pattern generator and i had to stop trying to get LUT unles Florian will add it to the program . Meanwhile i bought Calman and will test it. Once PI will be added then i can donate and come back to LUT.
My expierience with DisplayCal was good just not sure how to calibrate my C8 since i cant change anything in TV or like in HCFR change settings in program. Maybe I dont understand how to calibrate it using DisplayCal. As for LUT it is easy but cant get good results before i ger automated generator thats why i asked for PI support.
