WHY 最初は OFTEN SIGNALS A CHANGE:
Because は contrasts, 最初(さいしょ)は almost always sets up a "but later…" clause. A listener hearing it expects the situation to have changed:
最初(さいしょ)は難(むずか)しかったがだんだん慣(な)れた。
(It was difficult at first, but I gradually got used to it.)
By contrast, 最初(さいしょ)に simply orders steps and implies no such reversal.
