Identify Quick View attributes on form attribute collection

On a form in Microsoft Dynamics CRM you can place a Quick View Form to show information from a related parent entity. I use javascript to dynamically retrieve all attributes on the form:

Xrm.Page.data.entity.attributes.forEach(function (attribute, index) { ... }

As of CRM 2016, this method gives me all attributes available, includingattributes from the parent entity.

Is there a way to identify which of the returned attributes that actually belong to the parent entity and are only available because of the QV Form placed on the form?
