No, it does not. I just opened mine today after the update and all looks normal on my iPhone 7. This just means it supports the larger screen and "notch" when running on the iPhone X, similar to how applications needed to be updated to support retina displays on the iPhone 4, the larger screens for iPad, iPhone 5, the iPhone * Plus models, etcetera.May sound like a dumb question, but what does a non-iPhone X app look like on the iPhone X? Truncated top?
Edit: Oops, sorry, I misread your post. I believe the applications that do not support the iPhone X natively will be centered on the screen, and will not change the color of the parts of the screen beside the notch. The area the application doesn't cover will just be blank.
