What I'm saying is as Toshinori Yagi and Izuku Midoriya are different (especially in body), so that can mean OFA is manifested in various ways according the user. For Deku in this case, OFA is manifested like a new and shiny set veins/circulatory system made of energy fluiding though his body. And All Might manifested OFA granting himself such musculous form. That's what I thought too since it's a mutation that can be given to another vessel.
