It is hard to tell because we don't know if the dip was minimal phase or not.I'm too stupid to figure out what that video should show me, but I measured my tweet before and after two high Q peqs, one were the response were flat and the other where there was a dip.
5000 hz and 9270 hz;

CSD shows the same, but this was easier on the eye. Ringing at 5 khz and no ringing where I just fixed the dip?
If you want to see the effect better in REW just take a measurement and at a frequency where you don't have any noticeable ringing add there a narrow band positive PEQ (like for example 10kHz, +10dB, Q=10) and the added ringing due to the filter both in the csd and impulse response will be nicely shown in the simulated responses.
