On image left the separation between the CZA and 46° halo is visible particularly well. The sun elevation is 28.9-27.6°.

After enhanceing the image in Photoshop the supralatereal arc becomes visible as well. Note: there is also an infralatereal arc on the right side.

Here the sun elevation is 21.5-19.6°. 22° halo still remains strong and tangent arcs are clearly fainer than 22° halo. My vote goes to 46° halo.
