LEDs look completely wonky, the magnet sensors are not there, hole pattern for through hole parts is inconsistent between pictures and none of them match gerber files or video. Amount of tiles on the board vary between 7 and 9. Size of MCU board relative PCB is way bigger than it should be in real life. And of course MCU board itself is also a mess.
It's already bad for the DIY project, but if you are selling something even a single crappy picture would have been better.
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.
The board is very odd.
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.
Did nobody look at the image after they generated it? If they live in a bedsit and don't have a nice windowsill, they could easily generate the background and if the product is vaporware they could drop a rendering over the top - I think that might actually be easier than training an AI on your product... I'll be grumpy at clouds next!
