Does Tim put on a persona?

Two Tims from the same trip to Ibiza last year. I spliced together two clips (not actually 12 seconds apart). First clip from Gaby's video, second clip from his. We all have bad days and times when we're just not in the mood to be around anyone. But he seems to act quite moody and standoffish regularly in her videos compared to his where he's always very "on" and full of enthusiasm.

Compare that to other YouTubers that feel like they would be exactly the same if you met them in real life. How much of what we see in his videos is actually him and how much is he playing the role of travel presenter?
