On the archway I have marked in red, you can see it is a separate archway than the underlying archway that we see on the door in the top image. This might give the illusion that there is a larger space through the red archway, evident in the green square in the second image at the bottom left of the square, there is tiling that leads to another area, this could be the area that is in green in the first image. However the archway in red itself when taken a close look at has an unconventional form, the bricks holding it up are not placed in a straight manner, it suggests the archway is not flat but curved in a sense as to which direction you go through it is brought into question. Looking at the left side of the red archway it suggests you could walk through to the green square area, but the top of the archway and the right side could suggest more alignment with the underlying door archway. This is done away by the tiles that lead inside to the green square, but how much space is actually available inside that square is to be determined, there could be another room inside that is not visible.
The door itself would suggest it is either the same door from the same side, or a different door in the same position (often if facing the same angle the doors might be used in this position) due to how it opens. That would suggest the area in green could be the same area in both pictures.
I think the idea that the specific structure surrounding the door is different has some validity if there is no heavy shifting of perspective to see an area that is not contained in the second image or for a more detailed perspective, the bricks and surrounding wall/ceiling are more worn and smooth in the first image.
