The impact site was still nearly black up to August 1, but now it is fainter. On August 6, also if the image was taken in a variable seeing, the spot looks like a dusky E-W streak .
More images will be taken.
See the comparison between images taken on August 1 (at the top) and August 6 (at the bottom)
