Vincent was very helpful in giving instruction and advice during the calibration. He talked through what and why he was adjusting settings and delivered advice to the appropriate knowledge level i was at. Job was completed in a few hours, although i assume if you have multiple HDR sources will take longer, and content looks good now. The most noticeable difference for me on the LG OLED55E6 is that i can watch sports without struggling with motion blur. HD content looks good and Dolby Vision content looks amazing! Netflix 4K seems to be hit and miss as they sometimes only send down in 1080 which is annoying, but not calibrators fault :) Highly recommend for anyone looking to get the most out of their Ultra UDTV
