There are many places across both Remake and Rebirth that you can point to this sort of thing; a place where the new games lack the bite of the original.
The most obvious example up until now is FF7‘s ‘Trail of Blood’, a truly iconic and creepy sequence in the original game that, in the modern version, replaces streaks of blood throughout previously shiny and sanitized corporate offices with a sort of weird glowing purple alien goo. The music is the same, but the mood is wrecked by the change; the sequence undermined.
To be fair, that’s the prime example because it’s the worst of the bunch. Most of the time, Square Enix’s careful recreation of scenes from FF7, even when changed, land perfectly. In fact, the second part of the Remake trilogy, Rebirth, never really misses. With that said, it’s also fair to say that on many occasions, the events it depicts lack some of the heft and punch of the original.
