Unlikely (unless it was unmalted wheat).
A well made wheat wort will be crystal clear, the haze comes from the yeast. Even the name Hefeweizen literally means Yeasty Wheat, the haze comes from a yeast strain that is very slow to flock out.
I routinely use 10% wheat in blond beers, lowers the colour a bit, helps with head....
More likely to be your yeast, if its a home cultured yeast, your culture could have drifted a bit, its easy to pickup a co-infection of a wild yeast that isn't going to change the taste too much but can be hazy, if you can taste any phenolic notes in the beer this is a very real possibility.
1469 usually produces very clear beers, it attenuates and sediments well, assuming its a pure culture I would be looking else ware, and probably not at a very small wheat addition either.
