If you're shooting 4K with an iPhone then obvioulsy you'll use iCloud (also 5GB) not OneDrive. Good luck with that.
If you're a normal person then you'll probably use 200MB (my wife) to 1.5GB (me) shooting jpegs. I checked my folders.
If you think 5GB of OneDrive is a suitable option for a pro/semipro/serious photographer shooting RAW then I suspect you may have more serious problems than OneDive...
