Another point in his favour may be the clear view of the phone in the thumbnail, considering that his target audience may recognise it by appearance. However, I still think he should've just said it in the title for everyone else, and for audience members for whom his video is their first exposure to the model.

Regarding the last section, though, I see clickbait titles less as 'it doesn't cover every nuance of the video' and more 'the title is overly reductive, genuinely misleading or pointlessly vague', unless there's artistic reasons it's that way. A review title should name the reviewed product imo; it barely increases its length and lets people decide better whether the content's worth their time without wasting any of it.

I also don't think a title summarising a video's central point well makes it bad. A good video doesn't just repeat different wordings of the title for 10 minutes, it goes into specifics to argue why that is. I sometimes see nuanced, heavily researched video essays get some comment like 'saved you half an hour, guys! (the main point in one sentence!)' because the video didn't... have some massive plot twist, I guess? And I don't get why people would approach informational content that way. It feels anti-intellectual. Maybe the Silent Hill nurses are a work of art; the video would only be bad if it can't argue that well or has a lot of fluff between the points.
