I think the issue there and in general is that images look great on the monolith when you're watching in person - but not so great watching on a 16:9 TV.  Wouldn't be surprised though if that's deliberate with the intention they'll work cropped for social media.

I'm not sure how much of an issue that is. 

Apart from when it's showing BBC News or programme branding, the monolith tends to be used for one of two purposes: 1) to illustrate an in-studio explainer with a sequence of images and captions specifically designed for the 'tall' format; or 2) to show 'illustrative' images related to the report/package that's being introduced.

For 1), it's like a vertical PowerPoint. We see a few images but these are rarely the focus, and are generally just tinsel or background to whatever captions are being presented. The captions/callouts are usually large and brief -- "£2bn over-budget"; "unsafe at any speed", etc -- and easy to read. When used for this purpose, a tighter, closer view on the monolith is often used, rather than the much wider shot used in the images above, which again makes it easier to see the content being presented.

For 2), where wider shots are used, as in the screenshots in my previous post, the monolith is generally used to show a few images relevant to the upcoming package, in much the same way that a static over-the-shoulder graphic would once have been used. In the images above, Fergus Walsh is referring to body and brain scans -- but we don't need to see the detail of those scans at this stage; it's merely an introduction, and the scans being shown on the monolith are just there to look pretty and be relevant to what the presenter is talking about. We can see a giant body scan, and we can see some brain scans. That's all we need to see during the intro -- the detail comes in the package. 

If the monolith were being used to present smaller, more detailed story elements that we're expected to read or focus on at a distance, I could see this being a greater issue. Given how it's actually used, I don't personally think it's a big problem.
