6 players in game "discovered while being violated"

[CallMeMrRef]

I know that there have been numerous posts on this issue over the years, but perhaps this situation is a little different.

1.7 seconds to go in 3rd quarter. multiple subs for team A (and the officials allowed them to come in sequentially - not the topic). Ball inbounded and the quarter ends. B coach alerts officials that A had six on the court. The official can count 6 as they have to walk past him/her to get back to their bench.
Does this satisfy "if discovered while being violated"? Or is the fact that the quarter ended and no official noticed the 6 players prior to the dead ball to end the quarter controlling.

Any different answer if not the end of a quarter and there is a violation and during the dead ball the official notices that there are 6 players on the court?
