With the moving video, it's even more apparent - as bilky references - that how much of the desk 'insides' can be seen in the finished product is clearly affected by how green the reflection is on the real desk. The bit (closest to the presenter) that looks clearer in the above image is simply where the desk sees through to the green studio floor, rather than the less 'keyable' green tint of the rostrum. Also worth noting that, in some of the later shots in the video, you can clearly see the desk microphones in the final image.
