Nice question op I get the direction where your question is coming from. When you make a transaction, your wallet, if it is an HD wallet will collect input from all the addresses available with balance if one address isn't enough to pay for the transaction. And that is the input you see. For the output, it's where the coins go after the combination the first one goes to the wallet or wallets you are sending to while the other go to a change address after fees have been deducted.

Now where you are getting it wrong is expecting the miners receiving address to display in your hash but it doesn't work that way. The fees go the the mining pools address but it's not visible via your transaction hash because your transaction hash is meant to display and show data and Time stamps for only your addresses and not the mining polls address.
