You’re correct. From playing, I was pleased to see that secret rooms (specifically the bombable wall in Tail Cave hiding a room with a secret seashell) was thoughtfully obscured.
It was interesting to see that Kaepora Gaebora fades out after a certain distance as opposed to flying in that direction forever, and I did occasionally notice the odd visual stutter when distant “rooms” repopulate with monsters.
A lot of care went into this remake.
