Yes, that is pretty significant. But, you're not comparing apples to apples if you are comparing the weight differences between Trinovids and Ultravids when you compare a 42mm objective to a 32 mm objective. In like size objectives, the weight differences between Trinovids and Ultravids are nominal. Comparing the 32mm Trinovid and Ultravid, one is 22 ounces and the other is 18, again, not enough to make a lot of difference, IMO.
