Can any native speakers weigh in on Dogen’s accent? And is his pitch accent course worth it?

Dogen is like the face of pitch accent, so I'm just curious if his accent itself sounds natural. Can you tell he's not a native? Is his pronunciation really so good that he can be called an expert on accents?

I feel like when I watch Dogen speak Japanese, he's like thinking about pitch accent as he's speaking. I'm not sure if this is true, but that's the vibes that he gives off.

I'm through video 10 of his course, and it seems like every rule he gives he's like "Do I recommend you memorize this rule? Mmmm not really." lol. I'm just curious if I'm actually gaining anything valuable.

Has anyone who has studied from his course actually gotten compliments on improvement of their accent from native speakers? Like has anyone gotten any tangible, verified results?

I'm not hating, just being a healthy skeptic. It seems like in Japanese everyone has something to sell.
