Now I thought that it was rather obvious, seeing as it followed on from a number of previous posts. However, for clarity, the point was that, when the dark winter skyline issue was pointed out to the production team, they made a big thing about those panels, in that they would move them across the dark windows and the colours would provide a pleasing backdrop to the presenters. Yes, they might still be using them, but with the presenters now sat in front of the one wall, the prominence of said panels and their alleged effectiveness is reduced somewhat, and might appear to be another change in order to improve things.
I apologise if my original point was not made in terms that were easy to digest.
