Honestly, it doesn't seem terrible. Try a little denoise first, pull a nice soft keylight key, fill in the middle bit with a hard fill matte. The highlights are definitely bloomed (and possibly clipped) but you might be able to get a nice matte by keymixing in a lumakey. You could throw the image into YCbCr colorspace to see if the chroma channels seem downsampled any and apply the trick Randy mentioned. The only time I've ever seen a key pull with one click was when a constant was piped in... Good luck.
