After duplicating the test, I determined that it was the bright logo from the DVD player's screen saver that created the difference it bar intensity, not the capacitor. So the boost section capacitor is doing what it's supposed to be doing.
I'm about the flip the set on its side and remove the bottom and parallel the damper diode.
You wouldn't happen to know if removing the Automatic Brightness Limiter's transistor would disable the function and leave the set running without the function? The reason I ask is that of all the places I've scoped, the ringing is most visible on that circuit. I also remember last time I worked on it, just getting the scope's probe near the focus lead gave a ringing pattern. Is it possible for jailbars to come from the tripler?
