The one exception? You yourself just mentioned 2.
1. If one is told to do something against Halacha.
2. That a married woman’s priority is to her husband.
And the married woman is not “exempt” from kibud ab v’eim. It’s only that her first priority is to her husband.
I was not asking out of ignorance. Only to point out that your absolute statement as stated, was incorrect. As they often are.
