I'm not sure I understand the problem you're describing? There was some additional clothing DLC announced prior to launch for watching 3 hours of Twitch streaming of BG3 (https://baldursgate3.game/news/announcing-baldur-s-gate-3-twitch-drops_74) , but that was separate from the Digital Deluxe DLC. Which as far as I'm aware didn't include any clothing.

I think I'm getting from what you're saying that the Twtich streaming DLC was mistakenly unlocked for Digital Deluxe Edition owners? But that it then was subsequently removed again? But if someone was wearing the clothing at the time it was removed, they're not now able to replace it with new clothing? Is that right?

I confess, if I ever had that Twitch clothing unlocked in my game then I never noticed it. Not that I ever went looking for it.
