Carrot was there to showcase the abilities of the Minks in a winning scenario of course the Sulong ability that was already mention by the dukes (who said they would have dominated the invaders who almost wipe out the country) to be a massive transformation, would be a dramatic reveal
Its the power up that gives an entire side of our army a fighting chance
Where as Yamato is just apart of her combat list, its an ability but doesn't need to be over blown, especially because she is put in a situation that even she herself said she wouldn't win
So putting an unnecessary amount of hype behind a reveal just for her to inevitably lose would be pointless
Which is why she showcased her abilities in the fight against a foe she wouldn't beat but still showed she was capable, showing her ability without undermining them because she already recognized she is fighting a loosing fight
Where as Carrot Sulong was over exaggerated and then proceeded to disable ships and beat fodder making her ability come off as just that powerful
The context to the reveals matter, its lends nothing to their candidacy as a new crew member, if that were the case then Dalton would have joined the crew given how his Zoan was revealed

Let me indeed, put the transformation of Carrot into context. This is not just the abilities of the minks that was demonstrated here, it was Carrot's radiance using that power. The subject of chapter 888 is not "the mink tribe" it's Carrot. And you can check no non strawhat has never been depicted like Carrot was in chapter 888. As a centerpiece of a master piece. None. Even some strawhats themself have never been depicted with such visual and narrative showcase.
So yes, we must put into context those two transformation, but we had to to it right. We have to put them into the context of the entire story to see why one of them matter so much.
Carrot's transformation was not just "over exaggerated" Oda made it look like a transformation coming from a 1001 night folk tales.
This is importante because it shows HOW Oda actually sees the protagonist.
