Are post CTC4 RCA color TVs really narrow band color

Are post CTC4 RCA color TVs really narrow band color?

I simulated the color amplifiers of the CTC7 through CTC12 and
find that they are wideband, going out all the way to 1.5 MHz.
They are 3 dB down at about 0.5 to 0.6 MHZ and then drop quite
a bit more slowly, with reasonable guesses as to
stray capacitance.

If they are narrow band this would have to be done in
the bandpass amp. Does anybody know. This would be easy to
see looking at stray color from a continuous video sweep
from a test DVD.
