The problem with this definition is that it relies on sensibility, which can be affected by many personal factors, making it difficult to evaluate objectively. Think people getting emotional over manga vs. trad will prevent them from perceiving whether there's any real soul to be perceived.
Common feeling of the Joconde following you around with that weird "unfixed" smile could be considered a typical example of soulfulness.
