Yellow-tinted photos issue in Lumia 1020 was a known bug fixed with Lumia Black update. When Developers Preview 8.1 came, the tint came back and it's still on in WP 8.1 Update1. IMO it's a thing that Nokia fixes in OS version for a particular phone model, but I can be wrong. So, the question is not to go back to WP8 but whether OFFICIAL WP 8.1 version for Lumia 1020 is yellow tint-free. It was never an app-related problem.
