Does the absence of a color shift with certain papers mean that Se toning provides no significant protection for images on those papers? Thanks.

No, it does. Some papers just don't appear to show the toning but it did happen.

No. The visual effect varies considerably by paper, and does not correlate with the extent of protection.
"Considerable" protection, though, may require more toning (more concentrated solution and/or longer time) than many older references indicate. More recent research suggests that the treatment traditionally recommended by Kodak for protection, relatively brief toning in Kodak Rapid Selenium Toner diluted 1+20 or 1+40, may leave much of the image silver unprotected.
