Hi,
Yes the first product variant is not load completely in the product page and the name of the product which is display is the name of the main product.
Because it is the name which is displayed in the product list, we didn't want to display a different name when the user open the product page, it could be confusing. But I understand that you want to display the first product variant name, with a little view override you can change it (in the "product | show_default" view).
