Is there any possibility to change the way how Keycloak displays pages for bad responses(404, 500)? Maybe redirection or changing template for these pages? Simple view of 404

"... As long as the URL of the error page includes the realm it will use the login theme for that realm. Otherwise it will fallback to the login theme of the master realm. ..."
Sure, you can use custom themes and templates for all kind of interfaces (Web UI, e-mails, error pages etc). You can also extend existing themes and partially override it. Please refer to the themes development guide here.
