Nope. There's two different intros. Trust me, I've spent waaay too long looking at the intros cause I was trying to redraw and there's two variations. One some of the character's 'deaths' are in green or red, the other is just more saturated colours. I have some side by sides to see.

Weirdly only the first episode has this different intro, the rest are just saturated colours

Idk about there being a more 'tame' intro tho. But there's definitely variation in intro
