Interesting question.
I would say yes, but generally over the years Michaels perfectionism has most definitely deteriorated. From the period where he cried after his breakthrough performance (Motown 25) because he didn't execute one move absolutely perfectly - to a point where he seemed pretty OK half-arsing a performance at MSG in 2001 and doing whatever it is he did at the World Music Awards.
But I think he's in a much better place that he was in 2001, and now may be in a better state to evaluate that going on stage and half-arsing a performance wouldn't be healthy for his career. I've always thought that he is very scared of furtherly touching his career. He has lost a lot. Including his love for Neverland, which he thought would never land. I feel that it would be heart-breaking for him if this was Invincible all over again - yet, he's scared to expose himself like he did in HIStory since, if that was rejected, it would be like a sword through his heart.
We'll see.
To be honest, I think a good performance... like, 'Michael Jackson' good, could be one of the best things he could do, personally and career-wise. Whereas a bad performance would destroy his confidence.
One thing I've always noticed is his covering of the microphone, during more recent eras. I think that's him being self-conscious of lip-syncing, yet being self-conscious of singing live also.
