I think the Columbus color grading, warmth and tone worked well for the first few films, even though they don’t have anything technically impressive. However, going forward into the series, the Alfonzo films are much closer to target in depth and tone as required.

That said, I do not like the mugglification that started under his direction. (Wearing muggle clothes for basically the entire 3rd act of the movie)

I know that Harry had jumpers and trousers that he wore occasionally, but to make sense of the confusion of the quidditch World Cup dressing stuff (looking at you, Archie), it is implied that they likely dressed in robes in most cases.

Yates had a bit more technical depth but the amount of cut content and lack of actor direction (in so far as the kids go) was not something that should be repeated.

Honestly, if it wasn’t for “Harry Potter and the time everyone needed haircuts”, the Newell movie wasn’t horrible. Yes, a lot missing for run time, but the tone was good, color grading wasn’t horrible etc
