I'm not seeing the freckling to be honest. Also not seeing any hint of champagne. I would expect the skin on the face to have a far more "pink" colour, rather than dark skin, which I would expect in a single dilute cream. I would also expect to see more dilution of the black points - champagne acts on black. Also, champagne tends to cause a rather iridescent cast to the coat, while this horse is almost flat in colour.
Without actual photos of the horse's skin and eyes, there is no way I am willing to say that it is a champagne.
