A very good one is in the episode that just aired which referred to the "Aqua Ranger". They didn't call it the "Ankylosaurus Power Ranger Aqua". They called it "Aqua Ranger". Therefore (Color) Ranger is the correct designation, with "Dino Charge" added for disambiguation.

Furthermore, since it is used only in the roll call and nowhere else in the show, we'd need an additional source to support that as the designation. But they all say that name is wrong. Toys? Nope "Red Ranger". Official website? "Red Ranger".

In short, the roll call is the roll call - it is not their designation. They are never called "Triceratops Power Ranger Pink" by anyone else - ever. So yes, the disambiguator is necessary. And the show does not support those names either, as they are not used outside of the roll call.
