Interesting point. I think you could characterize "being conquered by the Portuguese in the first place" as a negative outcome, so there's a plausible argument that the Portuguese were more willing to embrace innovation, which is how they gained the ability to conquer the Tukanoans in the first place.

On the other hand, if you dig into the history of colonization, indigenous cultures had a massive home field advantage, and it was common for Western colonies to utterly fail, either starving to death in the same lands that indigenous people were able to survive in or in some cases, completely defecting from their original culture and joining indigenous populations.
