I've found the kernel code that is not processing this key-event.
https://github.com/torvalds/linux/blob/master/drivers/platform/x86/dell-
wmi.c#L218

Is there any way that the event is NOT ignored by that code in the case
of the Dell XPS 15 9550? (It was initially designed for Dell XPS 13
9350, where the intel-wifi-driver handles the hotkey event)

I'll try the kernel mentioned by @jsalisbury
