Maybe it's because I've seen way too many troon voice training videos over the years but I don't think his voice sounds good, and when I heard it, I instantly thought "Yeah, that's definitely a troon."
Sure, his voice sounds much better than typical zero effort troons we see on here, but it still doesn't sound right. It sounds like a very typical troon voice of someone who knows how to sing and knows how to control their pitch and etc.. Look up other troon singers and they sound the same:

It's kind of like how most pooners always have the same T frog voice, even troons that put in a lot of effort tend to all have the same sounding voice. There are very few post-puberty troons that have a convincing female voice.
