The project was ultimately abandoned with less than 20 seconds of film shot, but six decades later modern Disney artists completed the film using Dali's original storyboards. The result is easily the strangest thing to come out of the Disney studios since... well, probably ever.

Goes to show you can work some of the themes in, but it just doesn't hit that sweet spot that is Dali.
I haven't seen the full version, so I'm not sure how the CGI is. However, the idea of it doesn't seem that far out of character. From what I could guess about Dali based on what I've read about him, if he ever had access to it - he is the type that would have used it. Even if not using CGI directly to make art, definitely there would have been some collaboration with those who could help bring the vision to life. The fact he got together with Disney at one point to do animation (a media he normally doesn't work in, and the closest comparable thing to CGI of the era) would seem to support the idea.
