A thought:
Hide the 'perception failed' popup to avoid player metagaming, but keep the 'perception success!' result.
At a 'perception success' result, have the camera FOCUS on the thing that was revealed for a short amount of time OR make it's glow last longer; more often than not, with me looking ahead for threats, a perception will succeed, I'll hear 'Oh , that should be worth checking out', only to scroll back and have no idea what was revealed because it was a: too small or b: isn't an obvious difference in the scene.
In BG1 and 2, there was an option in the menu to auto-pause the game when spotting something passively. It's a bit weird that you often spot a trap and then immediately trigger it in BG3.
