In most cases the booth is smaller than the design area needs to be so every booth I've ever designed has been every sprinkler in the booth and throughout the plenum and exhaust, so you would be calculating the booth according to NFPA 33 not NFPA 13, the phantom flow is for NFPA 13 calculations
NFPA 33 9.6.2.1 The sprinkler design area shall not be required to exceed the area of the booth or room in which spraying or resin application is conducted. 9.6.5 The sprinkler system shall be controlled by a separate, listed indicating valve(s), operable from floor level. 9.6.6 (6) The system demand shall include the discharge from the hydraulically most remote adjacent sprinklers in a common 30.5 m (100 linear ft) area of duct (horizontal and/or vertical). (4) Sprinklers shall provide a minimum flow of 114 L/min (30 gpm) per sprinkler at a minimum of 1 bar (15 psi) pressure.
