It seems that death eaters have “anti-time-looping wards” (chap 94), we don’t know exactly how they work, nor if they were used in the graveyard, but it could very well be that no time-traveler can check the events that happened on the graveyard.
I myself will guard this place until six hours have passed, for I do not fully trust the wards I have set; and four of you shall search the surroundings for signs of anything noteworthy.
Would you risk going back to a live LV just to check it out? Take the risk that Harry didn’t notice some annoying bystander get dispatched, or just didn’t mention it? A lot of those revelations only came out when the subject came up, after all. Using a Pensieve would be much safer.
You assume Snape isn’t one of the headless minions on the ground...
Snape isn’t, because he can’t apparate from Hogwarts. Amusingly, Snape may interpret his exclusion from the mass sacrifice as a deliberate “kindness” from the Dark Lord.
Also, won’t anyone go back with a time-turner to check Harry’s version of events?
Also, won’t Snape know?

They were used. Voldemort mentions not completely trusting them.

Just watch from a distance, using a telescope.

I assume Harry will have to tell part, though maybe not all, of the truth to the remaining members of the Order of the Phoenix.
Didn’t Snape die?
