I didn't mean to throw shade on any particular methods, I was just trying to point out that this is a classic "you can't get there from here" problem. Nothing you do to an SE source will make it look exactly like the originals, so it's a matter of prioritizing what matters most, shot-by-shot. You can match colors and throw out detail, you can match detail and throw out color, you can match color in some areas but not others, and so on. The only guarantee is that there's going to be something demonstrably wrong with the result. The hard thing is trying to balance these tradeoffs to produce something that looks close enough, while not introducing new problems. Any of these choices is "making another SE" in a sense because it's just not going to exactly match the originals. Harmy chose one path, but there are thousands of others you can choose as well.
Again, using actual original source material, this all changes.
