Self-leveling basement floor. Does this look right?

[McKinly Springer]

We hired a contractor to renovate our basement, and they just "finished" self-leveling the concrete floor and framing. The floor has quite a few issues (high points, low points, pitting, flaking over an 8 sq ft area where there was a plumbing leak that they caused, and many sections are still wet even after a week). It looks like it might need to be redone, but the contractor assured us he'll just take a grinder to it and it will "look good" at the end. 

We're worried the LVP flooring we want to install on top will be wavy and that the floor isn't level enough. Based on the pics does anyone think otherwise?
