It's weird to publish an image that is horizontally mirrored (look at where the cursor keys are) without comment or just fixing it. Cute machine though.
At the same time, the wallpaper says "Sipeed" instead of something mirrored like "beeqiS". Weird...
Contents of the display are often added after the fact in marketing materials. The person adding the wallpaper probably just didn’t notice the photo was flipped.
