FWIW I can identify three separate pieces of material falling away from the upper part of the main tank. It appears that the first disappears from view then two separate pieces appear then one seems to strike the leading edge of the wing. Watching the trailing edge of the wing as the video plays a small cloud of debris or vapor appears just before the most significant cloud. The second big cloud of debris then disperses and as some of it crosses in front of the solid fuel booster it appears to be orange and two rather solid pieces track across in front of the white background of the booster. They appear as two orange streaks.
Now for speculations about that. The orange color could be reflection of the flame of the booster, especially if it is water vapor. One of the second two pieces of debris looks like it hits the leading edge of the wing just before the big cloud of vapor/debris. Could something have hit the leading edge of the wing traveled under the surface or inside the wing frame and then resurfaced out of the center of the wing? At any rate it seems that at least two objects struck the wing.
It doesn't change a thing, God rest their souls.
