Cloudiness/condensation look in my diamond?

The first thing I noticed was 1/4 of the ring is darker than the rest. There are some inclusions so I figured they are casting a shadow or something. But lately I’ve also noticed general cloudiness to the ring. It almost looks like condensation inside the ring which I feel like isn’t possible. I soaked the ring in water with dish soap, brushed it with a toothbrush and dried well with a lens cloth and it still looks cloudy. I’ll attach the GIA report in the comments. What is this and is this normal? Does it make sense based on the report? Thanks!
