Should I calibrate my TV?

Episode 1396 (56:30)

Tracy from Manhattan Beach, CA
Digital Video Essentials: HD Basics

Tracy just replaced his Pioneer Kuro with an LG B7 OLED TV. Scott says it's a pity he had to, because it was the best TV ever made, but all good things come to an end. Should he calibrate the LG OLED? Scott says he can pay a professional to calibrate his TV, but he can get about 80% of the way by selecting the "Cinema" mode in the settings. He can also get HD Blu-ray DV Essentials to help dial in the settings. Calibrating it perfectly will cost him several hundred dollars, but if he paid thousands for the TV, that could be worth it.
