Let it fully cure (as stated). The color will lighten up.
Its not going to be the same "exact" color and detail-finish .... as the old, worn, aged, exposed and walked-on concrete.
I think your expectations are not very realistic.
....not every company uses the same formula, or even the same ingredients. Even contractors in the same area may use different brands. Because of this, new or replacement cement will almost certainly not initially match the tone of the older cement. There are some ways to artificially age and darken new cement, but matching 100 percent is difficult....
FWIW - I have a standard clause in all my contracts that state that same point, for a variety of finish materials (No way to guarantee that new - will exactly match old. In somer instances, the only way to match is to go all new). This helps to manage expectations.
