Technology is great, but it doesn't overcome psychology. If the OP has worked as hard as he has stated then he's in a good position to interview. There are only two possible outcomes. Yes or no. If the OP goes the extra mile and does the Live in Person event and doesn't get hired then he can regret that he didn't get the job. If he does otherwise he'll be faced with two regrets. The first would potentially exist one way or the other. The second regret is of the if-only type. If only I had done the Live in Person event I would have gotten the job. Regret is a powerful and potentially debilitating emotion.

The other psychological aspect of the scenario is the psychology of winning. He's prepared to win if he does everything possible. If the OP does everything possible then it's likely that going the extra mile will improve his psychological outlook and this could be a deciding factor in the outcome. If only one of two candidates can be hired it might tilt the tables in favor of the candidate that appeared to be the most prepared.

I'd say that a great way that the technology could be used, and address both issues is in the case where the interviewee can't attend a Live Person event. Say, the interviewee is on a ship and the interview is the day after he reaches shore. In other words, it was impossible to do an in person prep. This person would have done everything possible and this extra effort can be a factor for him in much the same way as the first interviewee.

Every pilot I've ever worked with (a thousand or so) had to interview for the job. For every pilot I worked with I'd say that at least one other pilot just as qualified didn't get the job. What was the difference? If getting hired at a particular firm is your goal then I'd suggest that you prepare for success.
