I came from a Sony 65XH9505 to my 77A80J. I think I was really lucky with my Sony XH9505 as it had a very uniform clean picture with no DSE or anything. I just couldn't put up with the blooming on that set. The A80J is really superior in picture quality 90 percent of the time or more. The banding shows up now and again if the content is right. To be fair as you said, the altered carbon clip has banding on my A80j and LG c7 in bedroom with me too. My Sony XH9505 didn't show anything in that scene, just a clean picture. Most people seem to say that most oleds have banding to some degree, but there are a few that say there's are perfect and doesn't show up at all in content. The chances of swapping the TV for one that is exactly the same seems high, or might be extremely lucky and get a better one.
