2018 Chevrolet Colorado - Blue smoke

Light bluish exhaust smoke all the time. Does not use oil. Dealership can not find the problem. No oil problems. They put dye in the oil to check for leaks. None found. Any suggestions? Thanks!
Bought new. About 1500 miles on it.

Keep all documentation.
Seems a wet and dry compression test is in order. Bot possible rings haven’t fully seated yet. That would be HIGHLY unusual in a modern engine.
Keep a very close eye on your oil level. I would check when engine is cold.
