A prompt is not a copy of the image
Reverse engineering recovers the description that would plausibly produce a picture like the one you uploaded. It does not recover the original seed, model version, or sampler settings, because none of that is recorded in the pixels.
So expect the same look rather than the same image. Composition, palette, lighting, and medium carry across reliably. Exact faces, exact poses, and exact text almost never do.
That gap is usually the point. If you wanted the identical image you already have it. What you are after is the recipe, so you can cook something else with it.
