Is the Kindle Paperwhite Signature Edition worth $40 more than the standard Paperwhite?

The Signature Edition adds an auto-adjusting front light, wireless charging, and 32GB of storage on the same 7-inch display. Reviewers across mainstream tech press generally say the upgrades are nice-to-have rather than essential — if you don't care about wireless charging or want to save money, the standard Paperwhite delivers nearly the same reading experience.
