I already got the impression that the AI review that I get after playing a game misses my worst moves. In one of my recent matches, the top 3 game changing moves were 13.6, 12.2 and 10.4 percent. All these moves were relatively early in the game (move 25, 14 and 15 resp.).
At move #189 my opponent (fortunately for me) failed to kill a crucial group of mine. This move would have changed my winrate from an estimated 95% to around 5%. In other words, it would have been game over for me. How come this move did not show up in the list of top 3 moves?
Does the review only consider the moves that were made? How come it missed this rather simple killing move. The move was simply to atari a group of 6. I then have to connect to another group. The resulting group has only 2 liberties and is already surrounded by my opponent. Two ataris later the group is dead. Very easy to see, once you start with the initial atari.

I don’t know how the AI missed that, especially since you’ve got a higher tier AI reviewer.
I ran a full review—moves 188 and 189 were indeed the biggest game-changing moves.
Since you’re asking how the AI missed them, you should know how the AI chooses the top 3 moves. It does NOT secretly run a full review and pull the top 3 moves from that. Rather, it scans the whole game at few playouts, chooses the top 3 moves from that, and then reevaluates just those 3 moves at full playouts. This lets you see the result almost instantly, but it also means that the AI will miss things it would have found had it run a full review.
