IF it is a silicone there is an awful lot of it on there. Did you happen to notice if the appeared to be a fabric scrim embedded into the coating?
It looks brand new. Im not sure how the weather is up where you are but most Acrylic coatings can not be applied if temperatures reach below 50 degrees otherwise the water either wont evaporate out fast enough and it will remain gooey for days even weeks and will wash off in the rain or it will freeze creating visible fracturing in the coating. A silicone would not do this and can be applied in cold (approaching freezing ) weather. Silicones do not require a fabric scrim. A quality acrylic system would .
The wrinkling visible in the photo down the length of the roof is due to moisture intrusion, so this tells me that there were certainly failures in the existing roof . A coating may help and even solve for a period of time no matter what the chemical composition.
Nothing about these photos tells me anything is wrong, other than some shoddy workmanship. If it is a silicone you will start to see some “tobacco staining” through the coating in a year or so. That roof wont be bright white for long, but provided the leaks were fixed it will provide about 10-15 years of serviceable life.
