It's similar to saying that any digital representation of an image isn't an image just a dataset that represent it.
If what you said was any sort of defense every image copyright would never apply to any digital image, because the images can be saved in different resolutions, different file formats, or encoded down. e.g. if a jpeg 'image' was only an image at an exact set of digital bits i could save it again with a different quality setting and end up with a different set of digital bits.
But everyone still recognises when an image looks the same, and courts will uphold copyright claims regardless of the digital encoding of an image. So goodluck with that spurious argument that it's not copyright because 'its on the internet (oh its with AI etc).
