1) The maze on the carton can't be solved.
2) Two of the maze walls appear to be smudged, but nothing else in the image is.
3) The floral pattern on the plate is messed up - it repeats, but berries randomly change positions and the leaves change shape.
4) The milk carton has a splotchy texture that's really common in ChatGPT-generated illustrations.
I suspect it's not 100% gen AI - for example, the sharp outline around an out-of-focus xmas tree feels like a human-made artistic choice - but I'd bet it's at least partly composed from AI-generated elements.
And for what it's worth, the image pretty consistently trips gen AI image detectors (e.g., https://hivemoderation.com/ai-generated-content-detection).
