The first time I saw this, many, many years ago I HAD to open the picture in Photoshop and compare colours in A and B squares. I was genuinely shocked to find out that they, indeed, are exactly the same shade of grey.

The orange stripes are exactly same shade.

That's a well-known illusion, of course, but I honestly don't think that it applies in this case. Don't forget, too, that the black PB360 has a white bezel around the edge of the screen. As I say, my practical experience, doing a side-by-side comparison of the white Opus and the black PB360, is that the case colour makes not one jot of difference.
