The first thing that I try after generating an image from DALL-E is using reverse image search. I do it on every image that I intend to use, more often than not, I find a very similar image, in this case I discard it and vary my prompts.

Can you give an example? I was also doing reverse image searches, and I havent seen a single case of an image being closely related to another unless it was used as the base for inpainting.
At first, you can experiment with "extreme" input that can cause overwriting like: a photo of Marylin Monroe, etc. To search using reverse image search I use yandex, and I downsample the image.
