Icon Composer preview and App Store icon look different

Hello,

I made my app icon with Icon Composer and added the .icon file directly to my Xcode project.

I noticed that the icon preview in Icon Composer looks one way, while the icon shown on the App Store looks different.

Details:

I am using the .icon file directly in the project I am not using an exported PNG for the app icon I did not add a separate background image The background was set with fill in Icon Composer The preview in Icon Composer looks as expected The App Store version has a different appearance

I would like to ask whether this difference may come from:

App Store processing caching or a recommended Icon Composer setup for background fill

If anyone has seen something similar, I would appreciate any guidance.

I can also share screenshots of the Icon Composer preview and the App Store result.
