Hello goldenfrog88,
Thank you for using Apple Support Communities.
I understand that you are running into an issue when restoring an iCloud backup where it appears to stall or freeze at restoring True Tone Display information. I would recommend taking a look at the following support article for troubleshooting suggestions with specific attention to the sections "If a message says that your last backup couldn't be completed" and "If you receive an error while restoring form an iCloud Backup". While you do not mention receiving a specific error or message, these sections should be of particular assistance in your situation. Additionally, there is a link there to contact Apple Support if you continue to have issues with restoring from backup.
If you can't back up to iCloud or restore from iCloud backup failed - Apple Support
Best regards.
