If you turn down the color to get monochrome, where does the Y transition appear compared to the Q transition?

When I did the filtering, there was no delay. That is,
Photoshop left the center of the transition at the same "time"
for each channel. I don't
know if it is supposed to be done in the camera chain. What I
did would be correct IF the camera chain does the correction
AND the Blonder-Tongue modulator does not.
In any case, You can tell for yourself whats going on
by looking at the B&W images I
posted of the individual channels. Its visible in the original JPEG before being played. Attached. Note that the Y really IS unfiltered in
this file ... you can see that in Photoshop by converting to Lab.
