I've seen a lot of bimaculoides, but I've never examined a bimaculatus up close (they tend to live deeper). That said, based on the published differences, I think it's very likely that you filmed a bimaculoides, not bimaculatus. The bimaculatus is supposed to have a blue ring "with radiating spokes". If I ever get a good picture of the spot on a bimaculatus I'll post it here for comparison.
Besides the difference in egg size, and the "spokes", I found one source that said that bimaculoides ink is black, while bimaculatus ink is brown.
for reference, here are the sources:
