Yes, the circuit simulators can be wildly inaccurate ... but I have the experience
(quite a lot) of measuring the various stages of my CT-100 with various
peaking coils and playing with the simulator until it matched the data. No
reasonable stray capacitance and peaking coil (there is only one) resonance
frequency will make the CTC 7-12 amplifiers truly narrow band.

Everyone call the later circuits narrow band, but all we know for sure
without tests is that they are equal bandwidth in all three colors. The
real bandwidth is likely determined by the bandpass transformer, which
very well may be truly narrow band.

Edit: Today I got the manual for the Heathkit tube color TV I had in the late
60s. It has a slightly different circuit with a small amount of negative feedback that
broadens the color bandwidth even more. And they give the response of the
color amp and IF. The result is, more or less, flat to 0.5 Mhz with a very slow
drop off to zero at 1.5 MHz. This is not narrow band like Q in a CT-100,
but not as wide as the I in a CT-100. It did have a very nice color picture,
but I never saw real color bars on it that I remember.
