Microsoft has begun rolling out an update to Insiders for its Word, PowerPoint, and Excel Mobile apps that begins testing the company's new Fluent Design aesthetic. The changes are subtle but are mostly apparent with the transparency in the main nav column. You can see an example of the changes in this image above (courtesy of Windows Central).
While this visual change is currently only available to Insiders, it's likely that Microsoft will push this change out to public users soon given that aspects of Fluent Design have already been incorporated into the public versions of the Store, Calculator, and Alarm & Clock Windows 10 apps.
