I recently purchased an Android device and have completed the migration from iCloud to Google Photos. Before asking for assistance, let me summarize the current situation.

After receiving my new smartphone, I signed up for the 2 TB Google plan and turned on the backup feature. My photos were previously uploaded to iCloud, via a 2 TB plan shared with my girlfriend.

My question is this: once I cancel the iCloud subscription, is there any risk of me losing any of my files or compromising their quality? Is it even advisable to download them locally as a precaution? Does my girlfriend need to do the same?
