I don't see these as "Transparent with Glitter".
They look more like a soft, milky, semi-transparent, sometimes pearlecent, plastic.
I think these "new colours" might show a need for Trans colours with values for Alpha, Luminance and Material.
Look at the trans-green Bar 4L and light blue transparent Lightning Bolt part, in the same video review, in the post from New Elementary.
And in the new Trolls sets there's also some parts made of felt or foam.
(I've updated my table above.)
