S3 Default Encryption, and individual object encryption settings

Greetings,

I need some verification on S3 encryption. We have multiple buckets that have default encryption enabled, however when inspecting the individual objects within these buckets, they say server side encryption is disabled, and they have to be manually toggled.

Does this effectively mean the default encryption is doing nothing, or is the encryption setting on the individual objects an extra layer of encryption?

The end goal is to have all of our objects encrypted at rest. But it's confusing as to whether or not that's happening.

Thanks!
