Obviously you never experienced being isekai'd.
Anyway, they said near-photorealistic (before RT) to "a new level of unparalleled visual splendour" (after RT).
XsS doesn't get the unparalleled visual splendour tho. Lucky for them, it is at least near-photorealistic.
I guess it’s ‘near photoreal’ if you’re on acid? Which of course I have never done, I don’t condone drugs use but I heard from a friend that DMC5 is basically like a bad acid trip? A near-photorealistic acid trip.
