The EntryIterator currently doesn't deserialize MarshalledValues as needed which would cause filter failures and the incorrect values to be returned.

This also means each key/value pair would need to be deserialized when applied to filter which will be slower and should be noted in documentation, but sent across as MarshalledValues?. The only other way is to use some sort of proxy for each object to force lazy deserialization on referencing a field when applying filter, but this seems overkill.
