Here are some pictures to see what I'm talking about


So my question is, what is the reason for this? I have a few theories.
1. In the trailer you can see Frieza did not have the lines on his arms or his armor when blowing up planet Vegeta,

but they added both in the actual movie.

So they may have fixed his design to match how it's supposed to look in dragon ball minus and the original manga, and they just didn't feel like, or forgot to make the changes to his arms and legs in his initial scene.
2. Frieza was not done growing in the first scene, and after the 5 year time skip he grew lines on his arms and legs.
3. Frieza just decided to modify his form, as he should be able to do.
So what are your ideas?
