BS admissions for post grade

My child i applying to Boarding school for a GP year.
He does lacrosse, theater and engineering. He sent a theater reel to theater department heads, with a short bio and show of interest. 3 showed great interest and requested additional interviews.
Other schools zero acknowledgment of email and reel.
Is it safe to say that those school will be flat out no at this point?
Unable to visit because of distance. Zoom interviews for all except Andover.
His stats from a competitive HS
first generation American Latino and college student
3.78
SAT 1440
ACT 33
Theater , lead roles
Lacrosse, some club, but live in California where its not as competitive as east coast.
thoughts?
