LargestContentfulPaint needs to know if an image is showing a fully-decoded frame. For an animated image, this can mean that the entire image is still downloading (so we can't check the status()), but if the current frame is complete, we can count it for LCP. For a single-frame image, "complete" is equivalent to the image download being complete.
