IIRC, FR had long ago proved the yellow/green thing is the bottom of her shoe. The black thing could be anything including her black pants billowing up.
No, the anqles don’t work for it to be her shoe. And there are other faces and equipment in the water that are not any of the passenqers in that plane.
Also, the police didn’t recover any socks, shoes, or bracelets. They claimed her unbuttoned sweater was there but no socks or shoes...
There is a LOT more to be said about this. But the diaper section has already arrived here so it probably can’t happen here.
