It might not be defective at all David. Perhaps 7 billion people experience this illusion it does not make yours defective. Your correct argument is simply you do not experience this illusion. This simply implies that your vision is different from all the people who do experience this illusion. Of the people who have commented on the illusion in this thread most seem to experience it.

And trust me I am not suffering from this illusion one iota.

Having said all that, while this illusion highlights certain aspects of the illusory nature of colour perception ... eg there are no grey photons coming from the picture on your monitor. So whatever the bluey grey component you might see it is done without red light. And even with the red pixels any grey you might perceive is not grey.

Can you just agree that there are no grey photons coming from the monitor? And in this sense it is an illusion?
