Studio C I think it’s the oldest studio it must have been around before E.

That's not why the main videowall looks 'washed out', that's because the pitch of the LEDs (i.e., the size of the individual 'pixels') is far greater than on the more modern panels in Studio B, requiring them to be diffused through a piece of translucent acrylic to blur the picture together. This has the side-effect of making certain images appear a little faded, though the degree does depend a bit on the backdrop. The problem with the newsroom backdrop is that it has quite a lot of grey in it, which will struggle to show up if it is too dark.
