I think it just depends what you expect when you watch him and what kind of humour you enjoy… I only found his vids after starting my “learning journey” but regardless of that it’s very clear from the get-go that his content is for entertainment so I would not stop to take any of it seriously from a playing perspective.
Personally, I love really blunt and dry humour which he has an abundance of, and for some reason the monotone voice really helps deliver that (if anyone knows the totally unrelated but equally funny YouTuber penquinz0 then you’ll know exactly what I mean). The running jokes about picks being blasphemous and him making jokey excuses to skip riffs that might actually be above his ability are all part of that entertainment. As has been said, he’s primarily a YouTuber.
When it comes to playing, Davie can make some very cool sounds yes… but if I want to learn something then it’s BassBuzz or Talking Bass all the way, and if I want inspiration then I’ll look to established musicians. 
It’s all good content!
