Is there a Bitcoin Core method that identify when a transaction in the mempool uses Replace-By-Fee (RBF)?

I am trying to track transactions in the mempool that utilize Replace-By-Fee (RBF). My approach involves saving the current transactions in the mempool and comparing them to newly added transactions. If a new transaction shares inputs with a previously saved transaction, I infer that it replaced the original transaction via RBF. In such cases, I save both the original and the replacement transactions for further analysis.

My question is, if instead of doing all this, is there any method in which the Bitcoin core to tell me when a transaction has used RBF.

How to compute MAST commit bytes in bitcoin payment?

Image
The hash digests used to create the commitments are each 32 bytes, so proving that a spend of Figure 7-6 is authorized (using a merkle tree and the particular conditions) and authenticated (using signatures) uses 383 bytes. By comparison, the same spend without a merkle tree (i.e., providing all possible authorization conditions) uses 412 bytes. Can anyone explain how to compute 383 bytes and 412 bytes?
