Watched the video. My verdict: I don't know.

There are two different issues being blended in the video. Content vs arrangement of information.

As for content -- I've never seen Dunn's book but nothing he highlighted was unique or original to me. I've been drawing, learning, and teaching a long time and these are simply concepts and techniques that I've learned over the years. They are fundamentally facts. Facts are not protected by copyright.

Arrangement of information: Given that this is a fact-based book that is designed to teach, the arrangement of information is important and is more readily protected by copyright. From the video there appears to be a basis for a claim on this point.

BUT Dunn has not seen the finished book. Amount and nature of infringement matters. The only way to properly evaluate is by putting each book side by side and carefully evaluating both. Ideally, done by an impartial third party.

Instead we are only seeing one side that is clearly highly biased.
