Questions about shiny legends caught in Dynamax adventure using cheat codes

[caterpillar888]

i have found certain cheat codes to make the legend shiny at the end in Dynamax adventure, but i am wondering if it is really legal, since although pkhex says it's legal and no flags, i noticed a difference in pid types of normal ones and those caught using cheat code: one is Xoroshiro, and the other none. So i can't help thinking if it is really okay for pid type to be none in dynamax adventure.

here are those codes: 

[Shiny Dynamax Adventure Pokemon (Hold R)] 04000000 015D6F40 34000A20 04000000 
[Shiny Dynamax Adventure Pokemon (On)] 04000000 015D6F40 D503201F 04000000 

I tried using the pid of shiny Kyokre obtained through cheat code to make another non-shiny Kyokre shiny, and it worked.  From this, I can say that these cheat codes don;t just simply force the pokemon in max lair to be shiny, because if it is in that cause the poke must be illegal. If these cheat codes really work, what's the mechanism? is it possible that these cheat codes do boost the chances to get shiny legends in dynamax adventure?
