iOS client update changed gallery background

The iOS client on my phone was auto-updated yesterday. After the update, the background color of the gallery view has changed from black to white. A dark background seems to be favored for photography (e.g. Adobe Lightroom, Apple Photos). Can I set my background back to how it was (black)?

Thanks for your feedback! We’ve noted your preference for a dark background in the photo gallery. We’ll consider this suggestion for the next release.
