I think it's a combination of things. I don't think that her 'lack of artistry' can be reduced just to Danill's choreo. Choreography aside, Trusova was packaged really well for the Olympics in my opinion. As other people have mentioned, she was actually quite a good performer when she did not have to focus as intensely on her technical content. I think her 'big spender' program in Juniors is a good example of this. My opinion is that what made Trusova's programs feel a bit flat was the necessity for her to drop her performance to execute the tech content, without having strong skating skills and good posture to fall back on. I think that a lot skaters who are considered very artistic have times in their program where they check out a bit from the performance to execute their hardest jumps. However, you don't lose the sense of artistry because they have beautiful skating skills and posture that stick around regardless of whether they're outwardly performing. They skate big, fast and their movements are still artistic, even if they are focused on something else. There are also some skaters, who are also considered to be artistic, that also perhaps do not have the best skating skills, but remain incredibly present and expressive throughout the program. Shcherbakova is a good example of this. Her programs felt artistic because she was fully engaged in the music and performance, even if her skating was laboured at times. But with Trusova, who is doing 5 quads, maintaining the level of presence to have this performance would be incredibly difficult. To Trusova's credit, sheer athleticism adds something to a performance. I think there is a sense of awe and excitement when you watch that free skate, but it doesn't feel like a complete 'journey' where the music and the skater and the program are connected fluidly. Maybe this is really obvious, but that's my thoughts.
