It appears that the cement portion (not the aggregate) is typical white plaster. While the quartz aggregate is mostly blue.
Am I correct or not? Do you know if a blue color pigment was added to the plaster mix?
In any event, I see what you are concerned about. The quartz aggregate exposure is not consistent or uniform. However, it generally never is because of how difficult it is to expose the quartz aggregate uniformly without causing other damage.

I suggest to purchase some 80 grit Wet&Dry sandpaper and sand the areas that have the most "cream" to see if you can make it more uniform. I strongly suggest that you do not do an acid treatment in an attempt to rectify. It is better to have some cream (cement) showing than the opposite, which means the surface is rough and overly exposed.

They do sell hydro-polishing tools that attach to a pressure washer. $1800 for the tool and you buy the diamond grit pads for it.

You can drain the pool and polish the plaster. Then refill. Polishing would create a much smoother surface and give you a lot more control over exposure and uniformity.

Maybe sell the tool on eBay when you’re done.

You are correct, the cement is white without any stains or dyes, and the aggregate is mostly white/clean with very little dark blue and black mixed in.

I appreciate your input. The pool looks better every month as the cream goes away. It doesn't look bad, it just doesn't look fantastic. But I'd rather deal with it than reduce the life span of the plaster.

Good. Joyfulnoise had a good suggestion about using a power sander for large areas, and that sanding will produce a much smoother surface afterwards.
