That is so much better. Was it not said the diffuser was mostly for the benefit of Kays 'soft news' show? Makes sense to get rid of it since she is away.
The diffuser is to stop moire effects caused by the pixels of the LED screen. Think the weird lines and circles you get if you try and take a picture with your phone close up of a computer monitor, except constantly moving.
The downside of the diffusion is that it also blurs light from the front, so when working close to the screen any light shone (or bounced) into the diffuser will be visible, reducing the contrast of the actual screen.
It may be that they've experimented and found that with the camera settings and distances they're actually using it's not as bad as they expected when the studio was designed, so have been able to remove them.
