Are these reflections real or Photoshopped?

5 flipped and transformed areas of the real scene

Taking the image with the archway as an example, this is how I believe it is done: I make it five different sections of the pictures extracted, differently moved and vertically scaled, and then the changed overlaps cloned to conceal these changes. There will have been some other postprocessing and cleanup too, of course, e.g. the reflection will have been darkened a little.

Within each of these 5 areas, the reflection is an exact copy of part of the main scene, with no change of real viewpoint visible within that (though there may be a slight extra warping on the archway, since that was a little more difficult than the others to get very close to an exact match).

Just to explain the animation below: I masked out took different areas of the reflection as labelled, colourised them so they could be distinguished from each other, changed them to 50% opacity, then flipped and transformed each one to overlay the relevant part of the main scene, so demonstrating where it will have been taken from.

Hmm... in case that animation does not play, here is the composite:
