For wits, the character is more of a starch haze than yeast haze. I cold crash for a day to drop the yeast and the starch haze is still there.
Think of it this way, you are going to toss those in the fridge for several days before serving, right? Anything that drops in a 1 day cold crash is going to drop in that cooling time anyway. If you go grab a wit on draft at your favorite bar, it has probably been at fridge temps for weeks.
