well there's a different possibility. i've seen this with w3. you could run RTGI and as a side effect it helps with reflections too. it feels like a similar story here
im just theorizing btw. w3 was another game where u had to run RTGI (you could only enable rt reflections rt shadows on top of it. but u had to run rtgi as a baseline)
see for reference
notice how RTGI alone improves reflections somehow.
maybe the way these two games implement ray tracing requires RTGI as a baseline to work with. IDK. but seems like a "trend" definitely. if one or more game enforces RTGI as a baseline I will be convinced that its a trend
