Unfortunately I’m not sure if the full water detail for Bora Bora can be salvaged. If you look at the highest level of detail in Bing Maps, this specific area is using inconsistent and incomplete imagery.
Perhaps they could use a lower level of detail to fill in the missing information, as shown in your screenshot, but I don’t think they’ve ever made an exception for that. When full-detail imagery is missing, the simulator simply seems to fall back on generic offline textures.
However, Moorea can be improved. Like the island itself (and sadly many of the islands in the French Polynesia), there are some cloud artifacts over the tropical water, but right now the in-game representation is blurring too much detail, and as the trailer shows, it doesn’t have to be.
