I can see the roof quite clearly in the first photo.
Tbf I was responding to the existence of themed roofs, not whether there was any ceiling visibility.
More importantly that photo is presumably promotional and very bright, in person it’s much darker and personally I found it both immersive and impressive. Here’s a video which is more representative:

I think these areas can be well done and certainly in Tokyo offered a very welcome relief from the climate! An equivalent of this at any UK park would surely be well received.
