Can the shininess of the Sinnoh Starters be viewed before choosing them in BD/SP?

Question

You see, I wanna shiny hunt Piplup for a Dream Team quest I'm doing, and I want to make the shiny hunt for it take less time than it needs. As you've got to wait through the cutscene of seeing Rowan in Lake Verity before you can get into the battle with the wild Starly.

Answer 1

No. It will appear shiny once the Starly battle starts.

Answer 2

No, starters in BDSP only show up as shiny once in battle.
