To be fair, in my example, it was a DM determining the outcome of the ritual, within the fair means of the ritual.I would say No.
IMHO, the DM should not be planning out how the encounter will go so stringently that the PCs cannot take actions within their means and powers. If a PC has the ability to X, the PC should get to X, no matter what that does to the DM's expected encounter.
A DM cannot know when or if the players will use a scry ritual, so therefore the immediate result of the scry is almost always done off the cuff, unless the DM has a second-by-second planner with the NPC actions spelled out. After all, Observe Creature is only 1-5 rounds long.
If the DM decides that there's another NPC or summoned monster or sister or lover or handmaiden in the room, it's perfectly acceptable. And if either NPC in the room can make a perception check of 10+level of caster, then it's COMPLETELY valid. Heck a 25th level Cleric NPC, per the DMG guidelines, can have a +23 Perception so they only need to roll an 11 to catch a 24th level PCs sensor.
Adjudicating a scry can be tricky, even for an experienced DM, but especially for a new DM.
