Ahmadinejad didn't publish one closed view of a corner of a room, he showed full view of his house in a video, from it's neighborhood, it's yard, down to it's rooms. so excuse me if I have no doubt in his life style.
and about your own example, it's just a proof of what I said:
1.you admit that your arrangement has been mandatory due to lack of space, what about Rouhani's house?!
2.even while your TV has been in the corner, still you have arranged your furniture around it, that's what sane people do. even if that supposed room of Rouhani's home was a personal room, still he had to place the couch in front of the TV, the only explanation is that the whole picture is a setup for the sake of photography.
It's your prejudice that doesn't let you believe it.
Ahmadinejad's car:
VS
Rouhani's set of cars in an illegally occupied land of his neighbor!
