HMD Barbie Phone (US Model) Easter Eggs Error?

I just got my US model in from Walmart today. Disappointed to find the lack of a white theme option, just “dark” or black mode for the main menu. The reason for my post today? Easter eggs. I get the attached error message when trying any of the codes. I read they may work on the stateside model but I am having no luck. Is there any one more tech savvy than myself that can upload the files themselves here for me? Not a huge fan of the basic B default wallpaper. Thank you times a million if so!
