Yes, mine is the same. It's the beauty of the quartz plaster, it creates a washed out denim look and it will change over time. I can't find a picture on my phone that shows mine, but it looks just like yours and my old pool was the same color and had the same river-like patterns. My neighbor has the same color and it is also the same way. I work from home so I brushed about 20 times a day while curing to prevent this, but I believe it's from the way the trowel it on and the top layer gets the cream worked up into it and when it dries it comes out like that. Luckily my plaster guys have a very nice pattern that makes it look like a natural flowing river. I'll post a picture later when I get a shadow and can take a decent photo.
