I'm afraid you're forgetting that it can also be a sign of *high*
quality when the opacity comes from the little "hairs" on buds and
young leaves. (Though that isn't too likely in a generic tea, I
suppose.)

That's a different type of cloudy that is usually associated with teas
that most people can't get their hands on. Longjing, some HuangShan
teas, Biluochun, Zhuyeqing and Qieshe high grades have these small
"hairs"; all greens. The OP describes what sounds to me to be some
bargin bin stuff that can be picked up at any Chinatown.
