I wouldn’t say it was non-committal to that theme.
Hela tearing down the mural to reveal the actual sordid history that ended up building Asgard is a very direct invoking of western colonialism’s tendency towards revisionist histories. Even though Hela is the villain of the here-and-now, Odin’s refusal to own up to his past is what sets the events of the movie into motion, in terms of creating a heartless despot like Hela.
Thor looking up at the mural in the 3rd act plays a big part in his pivotal moment of realizing that the only way to resolve the sins borne from colonialism is to tear down the system that benefited it, here represented analogously as Asgard itself. The narrative also makes it clear that the current society of Asgard are not directly responsible for the corrupted system, but still benefit from it regardless.
It worked a lot better for me than Spider-Man Homecoming, which seemed to flirt with issues of working class struggles and the need to impress the ruling class in order to get ahead in life, but in which none of those themes tie into the main arc of Peter Parker or the film’s villain. It all seemed very toothless in a way that some of the worst Marvel movies tend to be.
Though I did like how Stark’s business was shown to dealing with these massive stockpiles of alien tech in huge warehouses for no real reason, which at least added to the analogous themes of upper-upper-class types being unapologetic wealth hoarders.
