headlight issue

have a 2021 sx telluride and noticed the other night my headlights had fogged up. is this normal because of the heat the lights are putting out and because of cold weather or are the seals bad?

My SX P passenger side headlight turns blue/purple within minutes of being turned on. My local KIA dealer has been very helpful, and apparently since it is LED they have to replace the entire housing (no bulbs). Anyone else with this issue? I included photos of what it looks like.
