We didn't even know for sure if Odin was alive or dead for years, that's how unimportant him being alive is, and the outrage over his death lasted just for a few seconds before Hela showed up, and that issue is never re-addressed or resolved because it's simply not important to the film or audience. Likewise, what does Asgard's destruction actually... do other than change the CGI backdrop for the exceptionally rare scenes in the MCU where Thor interacts with his people?
Contrast with Logan, we spend minutes at a time building the sense of family, and Xavier's death destroys that, paralleled with the destruction of an actual family, and changes the rest of the movie. Logan's impact on the the world of the film, not just other films, is clear, and his death is constantly being built up to as he slowly dies and shows he's aged. His death means something profound because it matters to the film, because it says things about the film in retrospect, giving a much heavier meaning. Odin's death says nothing about most of the film, if only because most of the film is on Sakaar. This is why Valkyrie's two minute context-free flashback carried more meaning than the death of The Allfather, because it was actually a part of the motivation of a main character, and not a plot device, clever as it may have been.
The whole rub with the speculation is that, since the events for Thor 3 don't impact the movie itself, several of the heaviest ones coming towards the end, the only consequentiality is to be found in other films, and those consequences are so easily and naturally sidestepped, calling the film consequential because of them sounds not just like an assumption, but a poor one. Again... the eye thing. It feels like a huge deal. In the film and the rest of the night, I was like "OMG THEY TOOK HIS EYE!" And the next day I quietly thought... "Okay... so?" And there was no answer. All of the big deals in the movie are a little like that.
