This study researched whether adding story elements to an instructional video affects motivation, emotional engagement, and learning. In the research, they explain that they did not find any difference between a well-produced instructional video and a storified instructional video.

However, the storified video feels very artificial to me. This isn't a story about a relevant character the learners can identify with who uses the concepts in realistic situations (or even slightly exaggerated ones). This is about a fake detective agency. I'd be cautious about assuming this research applies to realistic stories as well.
