In fact thats a example of the damage that can be done by looking at
scopes. When the first masters were made of Electric Ladyland, the
engineers looked at the tape, and found all sorts of odd out of phase
signals on it, so they decided to fix it. When the resultant pressing
was heard by Hendrix, he was less than impressed, they had spent a lot
of time creating all the out of phase effects in the first place. Thats
why its the second pressing is the one to have, not the first.

I call BS.

looking at a scope with simple waveforms on you may be able to see
out-of-phaseness.

I challenge you to do so on a complex musical source.
