主账户的待遇是要好一点的。主账号和附属账号区别如下：

Here are the key differences between extra member accounts and typical member accounts:

Extra members can watch Netflix on any device, but only on 1 device at a time.

Extra members can also download titles, but only on 1 phone or tablet at a time.

Extra members can only have 1 profile and cannot create additional profiles.

This profile can be a new profile or an eligible profile transferred from the account owner who invited the extra member.

This profile can have different maturity ratings, but cannot be a Kids profile. Learn more about Netflix parental controls.

Extra members must activate their account in the same country where the account owner started their membership.

Example: If the account owner signed up in Costa Rica, the extra member must create and activate the extra member account in Costa Rica.
