I'm thoroughly convinced this was done on purpose. The same way there were a lot of issues last year that stopped you from putting completely real looking uniforms out on the field, despite coming out the gate strong this year they went and messed it up and never fixed it.
I think NFL owners don't want you to be able to perfectly recreate teams with their identity. I think they want there'd be some visual flaw. Last year it was the bumpers and chin straps being the same color as the helmet, only one texture of helmet, the jerseys and pants having that diamond pattern.
