Hello @agoulet,
Clean Commerce theme does come in support for the Woocommerce plugin integrated with the theme. However, with the latest version of the theme currently the theme does not declare the support for the multilingual plugin like WPML and hence does not have the integrated feature for the multilingual logo feature in the theme.
We do appreciate your suggestion for the integration in the theme for multilingual usage and will consider the feature request for upcoming updates of the theme.
Also, for the current version, you can try creating the child theme to use and modify the logo for multilingual sites. Please check the references below that discusses the similar requirement and suggestions on getting the feature :

If you need help with the code customization for the features specific to your site you can also consider Hiring a professional customizer to modify the theme for the additional feature.
Hope this helps,
Best Regards !!
