Maybe it's like that weird space is a temporal distortion we throw the pokeball through to get "past" or "future" versions of our Pokemon.
Past form will dull their colors to make them look "old" and give specific stat buffs.
Future form will make their colors brighter and shinier to make them look "sleek" and give opposite stat buffs.
Then of course some Pokemon would get full on form changes when they go to either the past or future as a kind of Mega Evolution thing or similar to Gigantamaxing vs Dynamaxing.
