Extract dictionaries from JSON where a field value starts with a certain string

I'm trying to parse this json so that I can extract all dictionaries from the input where the "uri" field does not start with the string "/themes"

  {"version": 0,"permissionMask": 2,"creationDate": "2022-06-09T14:42:41","updateDate": "2021-11-17T06:48:52","label": "webPageView.css","uri": "/themes/default/webPageView.css","resourceType": "file"  },  {"version": 0,"permissionMask": 2,"creationDate": "2022-06-09T14:42:43","updateDate": "2021-11-17T06:48:48","label": "workflow_icons_sprite@05x.png","uri": "/internal/default/images/workflow_icons_sprite@05x.png","resourceType": "file"  }

so the output would only contain

  {"version": 0,"permissionMask": 2,"creationDate": "2022-06-09T14:42:43","updateDate": "2021-11-17T06:48:48","label": "workflow_icons_sprite@05x.png","uri": "/internal/default/images/workflow_icons_sprite@05x.png","resourceType": "file"  }

I've tried

jq -r '.[] | select( .[].uri | ( startswith( "/themes" ) | not ) )'

but that doesn't seem to work. It simply dumps all the output without filtering out the dictionaries where the uri field starts with "/themes"
