Really, these are the only 2 situations where ray tracing makes much of a difference. We already have simulated shadowing in many games and it works pretty well, actually.
Silent Hill 2 Remake and Black Myth: Wukong both have a meaningful amount of water in them and are improved visually with raytracing for those exact reasons.

Can you please point at the mentioned effects here? Immersion in what? Looks like PS4-gen Tomb Raider to me, honestly. All these water reflections existed long before RTX, it didn't introduce reflective surfaces. What it did introduce is dynamic reflections/ambience, which are a very specific thing to be found in the videos above.
does improve immersion and feels nice to look at
I bet that this is purely synthetic because RTX gets pushed down the players throat by not implementing any RTX-off graphics at all.
Just taking this one, you actually make a point about having a raytracing-ready graphics card for me. If all the games are doing the hard and mathematically taxing reflection and light-bouncing work through raytracing now and without even an option for non-raytraced, then raytracing is where we're going and having a good RT card is, now or very soon, a requirement.
