So, given the subject of the thread, let's talk about how darkvision impacts those elements of dungeon exploration.
I'm going to use a vague "night vision goggles" definition of "darkvision" here, just because we are talking about more than just 5E.
If the players are relying on darkvision, I think it is not just reasonable but required for the Gm to give them less information than if they rely on bright light sources. Darkvision is going to obscure details and even distort what the characters see. They may also have to rely more on their other sense, particularly touch, to get a full picture of their environment -- and touching every random thing in a dungeon is a baaaad idea.
If the fun of the dungeon crawl is discovery, then players should be inclined NOT to rely on it because they are limiting their own fun.
