Itzy like Twice have a very prominent brand
Ityz are a high energy/dance break intensive group, their new song is not that.
The public seem more open to variety from a group when they can showcase talent and JYPE are the worst at that. Itzy like Twice are just not taken seriously as musical acts, they are as kpop as you can get in how they are perceived. It's why both groups have such bad b-side performance in SK compared to their peers as well.
They tune to the groups for a certain type of song, visuals and choreo which you get for title tracks but that's pretty much it.
We'll see what they do next because JYPE definitely do care about the Korean market/perception there and currently all their artists are not doing that well there. Their biggest act in South Korea is Junho as an actor in recent times.
Even JYP couldn't break the top 100 on Melon despite all the promo, pretty sure it's the first time I've ever seen him miss out on even getting to the top 100. With his ego there's no way that's being missed whilst all the other labels lap up hits and Daesangs.
