Now that 4k TVs have got traction last 2 years and people are buying 4k TVs worth Lakhs it's worth spending on calibrating 4k TV for best picture quality. In UK and USA there are TV calibrators who come to your house and calibrate based on the room conditions like distance, brightness etc. Famous ones are HDTVTEST AND Darko calibrations. The 4k picture tv settings with multiple picture modes and Multi HDR adds to the complexity for common person for optimal settings. So my question is are there any 4k tv calibrators in India? If yes what do they charge?
