Not sure what you mean by looking weird. One thing about that jet is it hit the water at an angle, so debris, bubbles, etc. would likely move forward rather than at all angles around it. It also is composed of all sorts of composite materials in its skin, plus metals like magnesium that may react to salt water immersion. Plus any number of exotic materials, batteries, etc., so I assume that lighter colored plume around it is some sort of material or fluid from the jet interacting with the water.

Just my guess based on experience with military aircraft, but I'm definitely no authority on what made that water around the jet look like that, nor a materials expert. Plus assumptions on my part to try to make it make sense.
