No matter how non-scientific the image is, the blue is definately blue and
very blue according to the RGB values. To my eyes it is very blue but many
people see it as white that is a big question mark to me.

I'm not at all sure that we can trust what we're seeing to be the same
thing. If I load your link below
<http://www.bbc.com/news/uk-scotland-highlands-islands-31656935> into
Photoshop and sample the colors of each the readout tells me that my eyes
are seeing exactly what I should be seeing. The image at left shows a
white dress with a blue cast (roughly R=130, G=145, B=190) whereas the
image at right shows a clearly blue dress (roughly R=60, G=70, B= 190).
So, if these are the same dress (and I assume they are) it's not me that's
confused, it's the white balance of the camera and any follow on
processing that has taken place. I will also note that the dress at left
in the same link is the same photo I had seen originally but from a
different source. This version I still interpret as probably white but
its blue cast is decidedly darker than the "same" image I saw from the
other source.
No doubt our visual systems are different but I'm not going to get worked
up about a clearly non-scientific color presentation.

It is not related to colour blindness, the percentage of colour blind
peoples are much less than that.
The colours seem not marginal, the one who see white and gold is very
firm about it and it is the same the other way round.
Correct the white balance is not the point, the question is why we see
them differently even on the same monitor.
