PIPEWIRE_LATENCY does not set JACK applications buffer size

I created a copy of the pipewire.conf file in ~/.config/pipewire with the following configuration:

  #default.clock.rate        = 48000
    #default.clock.quantum     = 4096
    #default.clock.min-quantum = 32
    #default.clock.max-quantum = 8192
    #default.video.width       = 640
    #default.video.height      = 480
    #default.video.rate.num    = 25
    #default.video.rate.denom  = 1
    
    #PIPEWIRE_LATENCY=128/48000 Carla
    #PIPEWIRE_LATENCY=256/48000 Zrythm
    #PIPEWIRE_LATENCY=4096/48000 Ardour

After editing, I tested and the following results are both before and after restarting the machine:
