Why is the white ranger's transformation different in Power Rangers Dino Thunder?

The Power Rangers Dino Thunder wiki page has this to say:

Tommy (known often as Dr. O) himself joins the team as the Black Dino
Ranger, and they are also later joined by Trent Mercer as the White
Dino Ranger, with the powers of invisibility and camouflage,
respectively. Trent must deal with the inner struggle of good and
evil, as Tommy himself once had to do as the evil Green Ranger, due to
the fact that he gained his powers from a raw Dino Gem in Mesogog's
lab, with the powers originally intended to be Mesogog's.

I haven't actually seen the series, but this passage leads me to believe that the Dino Gem that Trent found wasn't exactly the same as the other two, and that's why his transformation is different.
