I doubt it is ai. The same room with the fireplace can be seen in both the picture featuring it and the hallway shot where it is barely in view, but the same furniture, blinds, rug, wall molding, etc. is visible in both. The apparent discrepancy in dimensions is likely the focal length on the lenses used.

The last shot is from the sequel. Same house still. But I don’t think that the after shot is necessarily the same room. The windows and fireplace placement doesnt line up.
