Galaxy S9 Display of background colour is broke

Greetings After I recently updated the S9 to the 15 April update of 10, 0.16-20210415110657

The Display only gets a dark or white background option under settings, the Contacts and Phone app stay white also the background for Contacts and for the Phone app, are white and cannot be changed, There are no settings to change the Display within those apps
The Display under Settings has no affect.
Is there a update to fix this? Can I back this update out somehow? this is totally broke.

Hope someone can help. Cheers, Luka
