To be fair, they were the last show to switch those credits around. All the way back in the mid-1990s, the Procter and Gamble shows (GL, ATWT, AW) re-arranged their end-credits and got people talking. Up to that point it was the writing team first, followed by the EP, then everything else. In the new order, the show's title obviously came first, then EP, then writers in the scrolling credits. They didn't super-impose any credits over the actual scenes, but it was a noticeable shift, nonetheless; the folks at the time theorized the production company wanted the EP to be viewed as what we today call the "show-runner" (top billing) as opposed to the past feeling that soaps were writer-driven. Soon the ABC soaps arranged their end-credits in the same way, and the Bell soaps were the only ones to leave their credits alone, mostly because the writers were also the producers and owners. Y&R and B&B were the last shows to still be run by their creator(s). But it was the Bell shows who started super-imposing certain crew credits over the opening scenes to resemble primetime shows, as well as crediting actors (with actor names onscreen) in the opening sequence, so they weren't dragging their feet on changes. Soon most soaps started letting the writers and higher-level producers names appear over the opening scenes, though the Bell soaps are the only ones who still include actors' names in the opening.
Ted Corday inherited Days from his parents who created that show, but I don't watch it so I have no idea where the parents' credit ends up as opposed to his. GH still credits its creators in the opening scenes alongside writers and producers, too, even after 55 years.
