Simon, it isn't a wind up! Make a screenshot, then open up in PS. Run the eye dropper over the middle of both sides of the cube, and the values are identical. This is a well known visual/optical illusion, otherwise known as 'simultaneous contrast'. I have always known that there is a world of difference between what the eye percieves and the brain (intellect?!) 'sees', and is the principal reason why I now work within a calibrated/profiled workflow by 'the numbers' - as well as by eye.
