Comparison of Star Wars: Episode IV - A New Hope 4K Disney+ vs Blu-Ray Version-
Cool comparison video, but it looks like all the laser bolts are washed out. There is a video for each of the first 6 movies.

Whatever sources they were using for the Disney+ comparisons were messed up, we discovered the actual video is much better. They also have “SDR vs HDR” videos, and that’s not how either of those formats work.
