The indicator just uses very generic names for tray icon, usually a theme will contain icon for application like nvidia-settings, the icon name will be nvidia, the indicator will use this icon instead of right panel icon.
The intel icon is right because there is no application icon using the name 'intel' in the theme.
@alim0x Hey there! My fork has some other options for icons as well as the default ones, plus some bug fixes and some new features. Check it out at https://github.com/andrebrait/prime-indicator

May be change the name of tray icon to
nvidia-panel
or so will be a better choice.
