To me this goes beyond a WB issue, as such it’s not a settings issue but a physics problem. And it appears especially evident as such with this statement.
It has been inferred but not mentioned directly, but to me it seems to be an issue with metamerism. As such the only way to correct it is in PP. You could do a custom-WB which may help the uniform color at the expense of the rest of the image color balance. It’s sort of a perfect storm of physics. It’s a fundamental difference between the way our eye/brain combination interrupts color and the ability of the sensor to record it coupled with the broken spectrum light source.
This is not a unique or rare issue and this topic has been discussed before. Just do a net search for “with digital image purple looks blue” and you will receive a number of interesting discussions.
