The tray at the top, right next to the mobile signal strength has a dot. Is this supposed to be the wifi indicator? That would make it different from every other Android phone.
The Wifi indicator is the same shape as other Android phones. That dot is an indicator that shows that there are more status icons than what are being shown right now. This happens due to the notch (limited real estate). You can see all status icons by dragging down on the status bar.
One way to create more real estate there is to disable battery percentage display.
