I haven't noticed this, also how exactly would OCR copy paste work? In order to copy text I would need to select text, which would mean it's already encoded as text.
OCR is regularly the easiest way to copy web page text on an iPhone by taking a screenshot first, and copying text from the photo. iPhone browser text selection is often broken.
Then again, a friend sent a screenshot of a contact and I asked AI to convert that to a vCard I could import (impressively saved time and was less error-prone).
