Sorry for my D&D ignorance but when you search a room for items, is there a skills or attribute check?
Maybe do something like:

No empty containers.

visible to all
Tier 0 objects : Empty but TRAPPED. (skill check, highlighted color depends on class/skill of the party) Every containers can potentially be a trap.
Tier one objects : mostly junk (opportunity for Larian to make funny or collectable junk...), MAYBE a useful item. (white highlight)
Tier two objects : Useful items. (green)

not visible, skills check
Tier three objects : hidden very useful item (blue)
Tier four objects: hidden very rare item (purple)

skills, class, attribute check
Tier five objects : very well hidden extremely rare items. (pink)

It just reminded me of the bowl of goat's milk that old Winthrop used to put outside his door every evening for the dust demons. He said the dust demons could never resist goat's milk, and that they would always drink themselves into a stupor and then be too tired to enter his room..
