something to add with encounters

Ive been seeing players getting annoyed, crying and sometimes flaring chat for accidentally running away from shinies and some other altered pokes. So i suggest, why not add something esle to indicate if the wild one is a special poke, like for example... ign vs wild shiny oddish, or ign vs wild pink caterpie, something like that... my core reason is that, many pokemons out there are too diffucult to distinguish if they are special or regular, a shiny seel seems like a regular one without that very small golden s to tell that it was shiny, nido m( i obviously let me pokedex opened and kept compairing like a color blind person), also another thing is that theres no other way to tell if it was really a pink nido m.
