I doubt it; in fact, if India can prove it killed terrorists, Pakistan would likely have little choice but to back off, as India would gain practically the entirety of international support.
No dear, rather than to accept in open that there were indeed terrorist, the wise decision would be to bury them in silence. Anyways, who is going to come crying and asking for their kith and kin who they sent to some training camp.
As I said, proofs will be furnished on need basis to international community which can help in deescalation. Providing proof to pakistani public will be counter productive and will put pressure on pak army to respond.
Even here in India, they are giving just enough to quench the emotions.
