To provide a fuller comparison, you’d need to also incorporate: share of viewing (per title), average box office returns (per studio eg Marvel/Disney), number of articles in mainstream media, etc.
For example, it could be that 10% of the films on that list are produced but never released (studio dumps, legal issues between producers and creatives, etc).
Just look at the USA box office impact of Black Widow, and Shang-Chi. Only two films but a huge proportion of post-covid box office revenue.
If Disney vanished from the world today, the dollars flowing to them wouldn't suddenly filter out to a bunch of niche and avant-garde media. There's some overlap, but people in that overlap are already into both things and funding them. The djent fans who also love a good radio-friendly bop are already buying djent albums on Bandcamp and listening to the radio-friendly bop on Spotify.
