TY so much for your comment & efforts!
I agree with your assessments but am unsure about the first in that after removing the maroon/brown spots from consideration if not required, the 3rd petal isn't pointed and much too blue, color of top petals too pale, and highly ruffled petals are anomalous. None of which may be considered diagnostic, IDK. Is there a hierarchy of characteristics, like striped spathes are more diagnostic than petals?
