So I'd probably approach by starting conversation with them about instagram. "Ugh, I hate that my daughter is on instagram now. It's so hard to figure out what limits to set about social media, especially as they're almost adults. What's your approach been?"
That way, you'll be able to get a way better sense of whether they know or would care based on their response. If they say "yeah, at this point we've decided she can use her own judgement on stuff like that, we're staying out of it" then you keep quiet. If they say "Oh, we monitor her instagram very closely, it is a pain" then you can say, "I noticed she had a second account - are you following that one as well?" or something that clues them in without being pushy.
I have a close and honest relationship with my sibling and I can’t even imagine playing games like this.
I would just say “hey, have you seen this?” and if they said “yes,” they would know I would take that as a complete answer and stay out of it.
Because I would stay out of it and let them handle it, but I would also never consider not saying anything if it is reasonable to think they might not know about it.
