Was there no real world testing before release? I feel like this is the same situation with permeable pavers companies sell to cities to reduce water runoff. Those are difficult to test (it's hard to measure runoff; me and me team wrote 3 papers on it), but this seems like it would be a lot simpler .. unless human beings walking on it all day have that much an affect on temperatures.
