True. It was/is also true with photographing monochrome sets where the scan lines are distinctly resolvable with black in between. As a kid, I tried taking some shots off the TV screen, and was always disappointed. Much later I realized what was happening. The bright lines were overexposed, resulting in the image contrast being compressed when the average was normal. A similar situation applies with photographing the night sky, where either bright stars will clip or many dim stars will not be recorded.
