Could you not use something like the "magic wand" selection tool in image editing programs? Doesn't the dramatic color difference indicate it's not part of the same object?

I thought maybe it grabbed it because it was the same color as the bouquet she is holding, but that is entirely within the white of her dress.

There definitely is room for improvement. Our proposed framework uses Mask R-CNN for object segmentation. However, Mask R-CNN only as a resolution of 28x28 pixels for the object masks if I remember correctly (which is then resized to the actual resolution of the object in the image). So there are a lot of limitations from that alone.

if you haven't already seen it, https://github.com/dbolya/yolact generates very sharp instance masks very quickly, may be of interest

Those masks look great, thank you for the pointer!
