Currently the branding process only affects new items that are created after the branding is set up in the Settings menu in the Admin Center. It would be ideal if there was a way to retroactively apply branding to previously created items. My company is currently running into this issue during the acquisition of a new company. The company we are acquiring has old branding that is no longer valid however there is no way to remove the branding with the current Smartsheet branding options. This means that the outdated branding and company name is still customer facing.
