Receivers do not report whether certain TP's are seen, only if the satellite is locked.
Even if they did, Dish uses the same spotbeams on different TP's in different locals. Too much data to handle.
Dish really does not care, as long as you pay the freight.
I've even seen posts where "movers" admitted blatantly to Dish what they were doing, and it was totally ignored, tacitly encouraged.
