In season 2 of Star Trek: Discovery, we join the crew in gradually learning more about
an entity known as the "red angel".
Until episode 2x06, the opening credits contained a blurry rendition of
the red angel
(right after the phaser schematic). In 2x06, the crew get a closer look, and it seems that for episode 2x07, the intro has been changed accordingly, as the blurry figure has been replaced with a
schematic of the red angel's space suit.
Have there been any other, more subtle changes to the credits in previous episodes? (Maybe like Game of Thrones, whose intro is modified for each episode to reflect the main places of action?)
