Hopefully it gets digitized and shared with the world!
If they control all the copies, then they can charge people to watch it, even if the copyright is expired. If a copy leaks, though, then that revenue stream will dry up overnight.
The raw scans were also provided to our counterparts in Cinemateca Brasiliera who are now in charge to decide about the film's fate. I surely hope they will make it accessible under a non-permissible license.
I home Cinemateca Brasileira will decide to screen it. Unfortunately, Brazilian culture doesn't get a lot of attention in Brazil.
It seems like the rest of the world cares more about our history than we do.
We had considered doing the scan in 6K, but the tests proved it unnecessary as it didn't yield any more detail except more grain from the film emulsion.
