I think photos are real, just focus is screwed up and maybe they added some automatic effects (tilt-shift or blur afterwards). First few seconds of the video are identical and you can see how much camera is fighting to focus when hand appears in the front.
Theyre messed up in a way that would only make sense if the image were AI generated because that pattern is trivially easy for a human to create but difficult for AI to get right.
An image or two afterwards has something strange with a table intersecting a window ledge too. It looks as if the AI attempted to do two images in one (like you see in some pictures of home designs). So I suspect all the images were AI generated but some more effectively than others.
Still I have no idea why one would do that.
The board is very odd.
