Yeah, I'm almost certain that it will just be chill haze.
All my beers used to suffer from this, even with whirlfloc and good cold and hot breaks I still got it. The beer is clear coming out of the fermenter as the beer is still at room temp, however, once chilled the proteins that cause chill haze become very visible.
Since I've started cold crashing and fining with gelatin, I haven't had any chill haze whatsoever. When I was bottling, about 3 or 4 days before bottling I would chill my fermenter down to about 32/33F and leave it at that temp for a day. Then I would fine with gelatin (there are many how to's online on how to fine with gelatin) then I'd leave it for another 2/3 days at that cold temp for the gelatin to do its work and then bottle as normal. All my beer came out crystal clear doing this.
Now that I keg, I simply rack from the primary to the keg, Put it in the kegerator to get cold for a few days then add some gelatin and stick it back in the kegerator. Using this method My first pull I get about 1/2 a pint of murky beer then after that the rest of the keg is crystal clear.
Hope this helps.
