Do you think this could be condensation instead of shock wave?

I have flown lots of supersonic formation and you don't see shock waves.
You can feel them though.

But as the pressure gets very low, you can see transient condensation of
water and this appears like shock wave.

Much like the stuff you see coming off the wing with high lift
configuration entering high humidity area.

And shock wave formation will kill lift aft of it pretty suddenly, no?
