I recently bought this Seamaster with a blueish/gray dial and had some time to take some photos of it today. It definitely is one of the toughest watches to photograph that I have owned! It appears to be the same shade as the uncommon blue/gray Speedmaster dials.
Had the same problem with the blueish grey dial on a C-case Connie (that I think I bought from you). Some colors just don't photograph well because of reflected light.
