When Design Feels Like an Upgrade (Without Changing Functionality)

I’m really enjoying the new screen glow when triggering Siri in iOS 18. It doesn’t actually make Siri better—the functionality is unchanged. But the effect makes it feel more advanced, more futuristic.

And you know what? I actually enjoy using it more.

This is a perfect example of how UI alone can shape perception.

For early adopters, it’s exciting—something fresh to play with. For less tech-savvy users, it could be momentarily unsettling… but in this case, nothing about the way you trigger Siri or consume the output has changed. Just the visual confirmation that something is happening.

It’s a subtle but powerful design move. No new functionality, yet the experience feels elevated.

How often do you use this in your designs? A purely visual change that increases perceived value?
