When?  Compared to the BIOS splash screen, for example.

It could mean it is done in the firmware.

What happens when you suspend the QEMU machine to RAM?  I believe the
tray should remain open or, if closed, should remain locked.  Can you
try the same test on bare-metal (hint: boot to emergency mode to bypass
anything that udev can do with locking the tray, then use sg_prevent to
toggle the state).
