The CT-100 can make an awfully nice picture. It's also complex and it requires careful setup. I wasn't watching color TV in 1954, but I wonder if many of those complaints were due to plain old misadjustment -- either because Grandpa started fiddling with controls or because the TV was never set up perfectly in the first place.
It looks like your CT-100 is dialed in very nicely, in any case. Impressive.
