Why are my app icons different?

First of all I wish you a nice holiday! But now to my question. I own the Huawei P20 lite with Android 8.0 and EMUI 8.0. But what I find surprising is why my Chrome icon and the settings is different than other models of the P20 lite and the same software.

Picture my icons

Picture as normal white is Quel

op = 1

I can't see the picture of your Huawei right now, but you have the possibility to set different designs. Possibly. Is the Android or App version another?

I'm sorry about the pictures but they were not uploaded
Do not know why
