Shake and spin the tyre. All of the little particles the sealant has to plug the holes are probably at the bottom of the tyre, and if they've been there for a while, they might not want to move at first. If that doesn't help, put more sealant in it, and shake the bottle too.
Those sidewalls do look more porous than some others though.
