It seems to me that HDR was invented with indoor shoots in mind. Nowhere else it can improve photographs in two ways, not just one. It not only gives incredible detail in the interior, main part of the shoot, but also lets you pick out of the windows what is outside :). In the image below, you can see through the glass door the deck, covered with blue tent and some sitting spots. At the same time, you can study all the objects on the fireplace. Nice.
