Even these examples aren't perfect.

The "Photos of Yourself in Different Eras" one said "Don't change the character's face" but the face was totally changed. "Case 21: OOTD Outfit" used the wrong camera. "Virtual Makeup Try-On" messed up the make up. "Lighting Control" messed up the lighting, the joker minifig is literally just SH0133 (https://www.bricklink.com/catalogItemInv.asp?M=sh0133), "Design a Chess Set" says you don't need an input image, but the prompt said to base it off of a picture that wasn't included and the output is pretty questionable (WTF is with those pawns!), etc.

I mean, it's still pretty neat, and could be useful for people without access to photoshop or to get someone started on a project to finish up by hand.
