Office Graph Disabled, Office Delve features have been enabled automatically

Customer O365 Production is configured to disable Office Graph, hence Delve is not available.

However in recent days we are seeing content, that was not showing up for the users on desktop browsers and mobile apps.

In browser we can see

1. News from sites on the /sharepoint.aspx page
2. Following
3. Suggested sites

From iOS Mobile SharePoint app we can see

1. Frequent
2. From a SharePoint Site on the app, we can see Activity
3. Content in the News Tab

What has changed in recent days to exhibit such behaviour? Office Graph is definitely disabled in SharePoint admin center.

Any one seen or experienced this? From end user perspective it means that SharePoint App (mobile) is now not showing Office Graph is required messages, but from security and compliance perspective we do need to understand, how/why this content is visible even when Office Graph is disabled.
