Your images didn't load for me, sadly. Might be some corporate filtering.
Anyway, I googled up this [1] article about supposedly original poke, and it also mentions rice and shows images of bowls with rice. Interesting!
PS. As a Swedish person, the "cinnamon rolls" with frosting that are typical in the US are somewhat triggering to me (because [2]). Sorry about the poke!
Edit: switched the cinnamon roll link to the actual Swedish-style image, for clarity.
