Stamping and Embossing

I recently had a large portion of my driveway torn out/replaced, a 12 x 18 patio poured, and 3 half moons steps poured, all of 6 bag mix concrete.

The flatwork looks great, virtually flawless.

The steps, on the other hand, don't.

After removing the forms/frame for the three steps, they were very rough, chunks were missing from the edges, etc. The contractor came back the next morning with a self mix bag of quickrete to "cream up the steps". He gave them a swirl pattern, which looks OK. The steps are however much brighter white than the flatwork, and there are concrete "spatters" on the flatwork. He says it will all blend together in a few weeks. It has been 8 days now, and it looks the same.

My two questions are:

1. Will it all really blend together and be the same color white?
2. Will the creamed area done the next day crack/break apart since it was added the next day.

I have pictures if that would help. Any advice/suggestions would be very helpful.

Thanks
