Thanks for reaching out via the Apple Support Communities. If I am understanding, when you attempt to change your iCloud profile picture in Settings > [Your Name], but when you get to the part of saving, it won't actually change. I'd be happy to help!
First, try restarting your iPhone following the instructions here: Restart your iPhone, iPad, or iPod touch. After the iPhone has restarted, try changing your picture again. Wait a couple of minutes after you select your picture to see if it changes.
If not, you can try updating the information using your computer at iCloud.com > Settings. Or, if you have a Mac, you can the settings under System Preferences > iCloud. Once you get to Settings on iCloud.com or the iCloud System Preferences on a Mac, just click your picture and choose another from your computer's hard drive. Additional detail on using a Mac to change your iCloud information can be found here: macOS Sierra: Change iCloud account information.
It may take some time for the change to update across all your iCloud devices.
