If SM is really planning to debut a girl band, will it flop as JYP's bands?

Other than korean charts Day6 flopped everywhere else and now extra heroes are flopping hard, to the point no one even knows about their existence. The rumors say SM will debut a girl band, and right now ggs are on fire but can a gb manage to take advantage of this or is just a mistake?

I don't know if it's fair to put Korean bands on the same playing field/metric as regular idol groups. They are after a different market and niche.

It would be more conductive to see how the bands compare against each other. Granted, I suppose the pool of bands is probably smaller to pull from, but I think you get what I mean.
