What details are you assuming Telegram are sitting on, besides the data law enforcement already collected?
Durov got arrested for insufficient moderation of public channels, so my guess is that law enforcement would be able to get exactly the same data as Telegram themselves sit on.
But it's hard to get a full picture without it going to public courts, for now we can only go on what's being reported.
