Different widescreen solutions I see. Network had black bars, NI stretched the reflection, and Wales actually has blue bars - so I'd say that is the actual NODDY system brought out of retirement, yes. NI's version used CG, so it could be wider than the original. Network's is stock footage from back in the day.
As mentioned in the comments on those uploads by D Page, Network last night appeared to use this recreation which is based on an actual model that the uploader made, which surprised me!
