Is there a way to differentiate between luminosity keys and escape key?

Question

While I was working on a pygame project, I noticed that when I change screen's luminosity the window was shutting down. The only key that is suppose to do that in my code is the "escape" key :

for evt in pg.event.get():
    if evt.type == pg.KEYDOWN:
        if evt.key == pg.K_ESCAPE:
            exit()

This works without any problem when I press escape.

The problems comes from the fact that changing luminosity acts exactly like pressing the "escape" key. I've tried to print both events and no matter if I press "escape" or if I change luminosity, the output is exactly the same :

(This is also the case when I press the "mute microphone" key for example, but for some reason, the "volume up/down" keys are not concerned by this behavior)

Is there a way to differentiate between those keys with events that look exactly the same ? I want my window to close only when I press escape, not when I change luminosity.

You can recreate this situation with the most basic pygame setup :

# Imports
import pygame as pg
import sys
    
# Init
pg.init()

# Display
WIDTH, HEIGHT = 500, 500
screen = pg.display.set_mode((WIDTH, HEIGHT))
    
# Functions
def handle_input():
    for evt in pg.event.get():
        if evt.type == pg.QUIT:
            exit()
        if evt.type == pg.KEYDOWN:
            print(evt)
            if evt.key == pg.K_ESCAPE:
                exit()

def exit():
    pg.quit()
    sys.exit()

# Main loop
if __name__ == "__main__":
    while True:
        handle_input()

Then try to press all your function keys one by one while the window is showing (and in focus) and let me know if you observe the same thing.
