I am currently using a Realme device which runs on Android 13, When i set my app icons to match wallpapers color a few of them are staying as they are as shown in the screenshot. Is there any way to customise these aswell with the help of any 3rd party apps? This just doesn’t look right.
It’s a new feature, and app developers need to implement it. Leave a review or a message to the app developer asking for the feature.

Alternatively, you can use an icon app that’ll “force” it such as icon studio etc.
