I get the feeling you're a bit muddled on how Bitcoin wallets actually work. You're mixing up terms and saying things that don't make much sense. All wallets nowadays generate multiple public addresses spawned from one original seed and this covers change addresses too. So there's no master address or single address that represents your entire wallet.
In the past, with earliest Bitcoin wallet softwares, there was no Deterministic wallets or Hierarchical Deterministic (HD) wallets.
Bitcoin wallets chapter in Mastering Bitcoin book is a good educational resource to learn about wallet development history.
Nowadays, we are mainly using Hierarchical Deterministic wallets that give us a Wallet seed, from which wallet software creates Master key, Child keys, Grandchild keys and so on, then different addresses for using.
