Let's say the group finds a corpse and that corpse is wearing a magic item, e.g. his shoes are magical. But nobody in the group mentions they wanna check out the stuff he is wearing. They might just end up giving the corpse a proper burial. Nobody used Detect Magic either. Would you as DM give them hints? Like "Something seems extraordinary about his clothes" or would you just be "Well if they don't want to search a dead body they have to live with not getting the magic item he is wearing"?
I always telegraph something notable when describing the environment. I mean, just look at the illustrations of the magical boots and slippers in the DMG - those things are notable. (I think I used to have those slippers when I was a kid and now I regret throwing them away.)
If the players don't choose to engage with the environment in a way that reveals the magical nature of those notable shoes, then that's on them. And it happens that way from time to time.
