Is there any downside to using this feature? it came useful a dozen of times where i zoomed out while editing many of the photos i took with my 11 Pro on a recent hiking trip and when i zoomed out the massive wide image that came as a result was much nicer than the original photo i within the standard 4:3 frame. Does the iPhone basically "stitch" the original photo that was taken with my iPhone's 11 Pro's main lens along with image data that was captured by the ultra wide lens while taking the photo and its all basically stitched together?

How does it work videos? (I dont see a way of editing a video to reveal out of frame data captured during a Video recording)
