Calibrating 709 and not 2020
I just has my VW995ES calibrated here in Tampa. The calibrator made adjustments to gamma, gray scale and color for rec709, but no color changes to rec2020. Should I be concerned? He said the changes to gamma and gray scale would be applied to both 709 and 2020, but only the adjustments to color would be applied to 709. Seems odd to me. Thoughts from the community?
