I used to think there was a solid story on leucistic black rats, but I'm not sure now. The main trait I hear of is that they are a lot more tame. A lot more tame is cool! But it's also a very subjective trait. I'd heard that leucistic black rats were also more white than TX rats.

There was apparently a new line of leucistic Texas rat that popped up out of the wild. They were being advertised at $300-$400. Great that it's a new line, but I think that's a bit much to ask for a morph that is already very common in the hobby.
