I thought his tree of life get Palme dor? And he also appear there for his hidden life. I know certain filmmaker like Robert Altman hate the flashy event like those during Oscar season. This is just their personality but believe me , they pay attention to what happened, maybe not religiously subscribing it, but they do. Filmmaking is a creative process where people, no matter how talented they are, is constantly seeking for inspiration. And works by their peers or competitors certainly draw their attention.
