I've been checked for vitamin deficiencies before, though I don't know if B6 was specifically checked. Regardless, they only found that I was low on vitamin D and so I do take a multivitamin, though I have doubts that it helps in practice. I have also indirectly supplemented vitamin B6 and B12 via frequent energy drink usage (not the healthiest thing I admit!). I notice no difference to mood, physical comfort, or ADHD symptoms on or off vitamin supplementation.

I suppose anything is possible, but from what I know -- I'm not a psychiatric professional but I've lived with one for 20 years -- it sounds unlikely to be true for most people with similar diagnoses. Believe me, psychiatric hospitals would love to make more beds available by "curing" mental illness with diet.
