If I encounter Shiny Tornadus before Regular Tornadus, will the Pokédex Page register it as Shiny (Read Description)?

Question

Feel free to change the title

I’m playing my Oshawott run and accidentally triggered the roamed cutscene. I saved right before exiting the house, and I know once I exit, a minute long cutscene will play and then suddenly Tornadus would be added to my Pokédex. To save time, I want to know, would the shiny sprite show on the Pokédex page instead of the normal, or do I still have to press “forms” to see if it were a shiny or not?

Please don’t answer if you don’t particularly know this shiny hunt since it’s a bit unique in terms of “encountering” and the last thing I want is to hear someone telling me how a cutscene =\= Pokédex or that I have to battle him or something

Edit: I’m not totally sure if this is comprehensible or not so here’s a video of me explaining the hunt and what I want to know

This says that, if the first Pokemon you encounter of a species is shiny, then it appears as shiny in the Pokedex, but I'm not positive it will do that for Tornadus/Thundrus, as it might just register the normal version in your Pokedex regardless of if it's shiny or not.

I can't see the image, so I don't know which page the shiny would appear on.

It should register as shiny, if you haven't encountered the original form of a Pokemon but you have encountered the shiny it should only show it's shiny.

I think it's clear that it will appear shiny in your Pokedex. I know this happens with every single other Pokemon encounter in the video game series, so I don't really see why it would change for this encounter anyway. I know that this encounter is different, but for example if you encountered a Cresselia or Mesprit in DP for the first time, it would either appear shiny in your Pokedex or not.

Edit: After watching your video, I can say that yes it will appear shiny before you hit the "forms" button because you aren't encountering two different Tornadus.
