I’d plan this as three distinct zones rather than make one wall do everything. Keep the TV and main seating on their existing viewing axis; put the study desk on a side wall so its task light and monitor do not glare into the screen; give the temple a calm, dedicated wall or shallow niche away from the TV and desk clutter. Closed storage for books, cables and media gear will help the room shift between uses without the study taking over movie time.

I’d also separate the lighting: dimmable ambient light for watching, a focused desk lamp for study, and a gentle dedicated light for the temple. If you use candles or incense there, allow safe clearance from curtains and electronics and adequate ventilation. A room photo or quick sketch showing doors, windows, wall lengths and the furniture you must keep would let people suggest an actual layout rather than guessing.
