It’s possible because they don’t want to completely invalidate the older solstice set this was based on. That didn’t have any white glows. It predated the money hungry solstice events where the white glows were the “free” unlockable gear and the colored glows required both unlocking and paying for the gear. Since I have the older solstice set I can’t see if it’s available in the store or not 🤷🏻‍♂️
