The umbrellas went from having futuristic light sticks for the handles in the original to being plain old umbrellas you can get in out timeline. I bet the clothes in this version will no longer have that blade runner look and will be the same style you can get in our stores. Harrison is already wearing a gray t-shirt and jeans. Gosling looks like hes wearing his regular clothes.
You can get lightstick handled umbrellas now. There's probably even a parent granted, so the film can't use them without buying those ones. Or they are going to pointlessly cgi in the handles. Or they forgot.
To be fair...that's because we now look like BR. And to an extent even some of those BR fashions were extant back then in some parts of the world.
