It hints at an ability for perceiving and accepting variety, and probably some measure of peace when faced with the idea that there may well be no sole, ultimate authority with supreme and direct power over every human being.
In very broad strokes, the affinity for perceiving discernible attributes and perhaps identities in the manifestation of the sacred tends to also suggest an appreciation of the very existence of attributes, suggesting a measure of artistical affinity and perhaps a bit more acceptance of variety of lifestyles and of the need for self-expression and self-discovery than a strict, emphatic monotheism is likely to accept and encourage.
On other hand, when contrasted with less mystical, more skeptic worldviews it also suggests more of a taste for the unseen world than those views are likely to nurture, and that correlates with a heightened appreciation of individual people, even of individuality itself, as well as with a sense of wonder and gratitude for everyday's miracles.
TLDR: Generally speaking, and of course barring evidence to the contrary, I would assume polytheists to be overall contemplative, to live in the moment, to have a well-developed sense of wonder, to have fairly good emotional expression and to be slightly more authentic than average. It may be more of a challenge to actually connect with them beyond the most superficial levels, though; there is a price to be paid for all that self-acceptance.
