This isn’t an “uncorrected mistakes or unfixed issue”, but it is a mistake and issue for the quality of image on the 2019 editions to be so lacking in detail:
@adywan you did you use sharpening tools just wondering Someone said this shot looked overly sharpened. It was on a discord
Well that shot is from 2 different sources, as was fully explained in the original post on this site where i posted that image. No sharpening was done. It was to show how much detail has been scrubbed from the 2020 blu-ray, which is the image on the left, compared to the detail in the 2011 Blu-Rays, which is the image on the right. The panels on the droid in the 2020 blu-rays have been almost scrubbed away including the weathering.
There are more examples in adywan’s “Star Wars: Episode IV Revisited Edition” thread, on page 490:
