There are.
The game has multiple cosmetic(?) DLC, like the Nier and Nikke crossovers, but for some reason they aren't on the Steam Store page like for every other game. They're included in the Complete Edition, and if you click on that bundle you can select and potentially buy each one separately.
BG3 and Cyberpunk have boobs and were a success, which would support that statement. But Wukong, Palword, and Monster Hunter Wilds were even more successful (according to concurrent Steam players), which means animals are the true secret to success.
