I'm pretty sure Trinitrons are always heavier than other monitors of equivalent size because of the aperture grill design. It let's more light pass through, making them brighter, but boy do they get stupid heavy as the size increases.
Yes, the aperture grille (hundreds of wires and a metal frame holding them in tension) is itself heavier than a traditional shadow mask.
However, aperture grilles also use differently-shaped glass from shadow masks. The screens are only curved horizontally like a cylinder rather than on both axes like a sphere. This requires thicker, heavier glass to hold the vacuum.
Later flat-glass shadow-mask tubes were much closer in weight to flat Trinitrons.
