I mean... I was talking about the game events, not events of the past, is like asking if you are still the same person you were when you were at elementary school or high school, people are bound to change at some degree, and trauma are bound to follow you until you die. Maybe you forget about it, but the memory is buried inside your head just waiting to get trigger by x reason.
Maybe is just me, but it would had been an interesting plot point if hc had harry have nightmares involving maya and luca to give more context or lore to the story but luca face would be blurry as an indication he still remembers him at some degree. instead of leaving it for an ending, that probably had added more flavor to it... just my two cents.
Edit: This was more targeted towards the endings rather than the story, sorry for not making this clear, but I still wanted to explain my point of view, so let's keep it civil
