Yup - the blue from the polariser would probably lend itself to an obvious manually added blue …. or just white … before uploading to Kuula.
It’s a great pic, though, that deserves to be seen properly in 360. I hope you upload. Don’t forget to post in the #panos category if you do … add to the Pano-Mania - (aka The Great Pano Thread) thread if you want.
