Also some dealerships are cool about small modifications.
most of the techs in dealerships nowadays do not check the tune of a vehicle unless you mention it or its completely obvious the car is heavily modded
I thought they have a way to tell that the ECU was flashed in the history or something. I think you might just be lucky with a dealer that's cool with ECU flash. I wouldn't risk losing warranty on a brand new car especially when you know there was a problem with it. There's no way to say the problem won't come back.
