not an artist but, reading between the lines, her real fight is against people who are copying. and profiting from her work. that said, i agree with the ruling. there are chances that other artists who haven't seen her art before would come up with that scene. or that specific pose. not the other artistic choices, but the pose and the flowers, and even the kimono, yes.
The face of the person in the painting is recognizable across the copying, I don't see how it can not be a copyright issue. Clearly cribbed her work completely and changed some color and details.
Cross-reference Andy Warhol's famous silk screens. For example, the reproduction of Elizabeth Taylor (https://www.sothebys.com/en/articles/andy-warhol-and-his-pro...) was sourced from a 1950s publicity photo.
