By right, you mean that it is fortunei, NOT ventricosa....aureomarginata
Your first statement in the thread is not right.
ventricosa Aureomarginata has some color blending and is creamier, lots more margin than your pic.
You probably have fortunei aureomarginata (and I can't say that is what it is for sure because there are some other hostas that look like it as well in pictures)
