I've no suggestion and never seeing O. bocki but knowing O. bocki looks something like an O. mercatoris, Roy's suggestion from the original picture seems like the best offering so far. I went to my journal for Espy and see a similarity in the arm stripes and basic shape but not the eyes or red coloration (I don't think Espy ever showed red). Here is one of Roy's photos of O. bocki . The color the eyes seem to be similar but not sure about those arm stripes (which is why I looked at Espy's pictuers). Octos can show so many color and pattern differences, it is hard to say if a particular species can/does show arm stripes and I have seen them on most I have kept but definitely not all the time. Here is a image I found that claims to be (in situ photo) O. bocki WITH arm stripes.
I definitely think it is nocturnal. You said you had hoped keeping saltwater tanks would increase your patience, enjoying a nocturnal will serve this purpose
