I think unless you can either (a) show that QEMU is behaving differently
from the real hardware or (b) point at what bit of the hardware
documentation QEMU's implementation is not following, then this doesn't
really sound like it's a bug in QEMU.

Title:
PL110 8-bit mode is not emulated correctly
Status in QEMU:
New
Bug description:
When the emulated pl110/pl111 is switched programmatically to 8-bit
color depth mode, the display is drawn green and blue, but the real
PL110 displays grayscale in 8-bit mode.
The bug appears in qemu-system-arm version 3.1.0 (Debian
1:3.1+dfsg-8+deb10u8) and qemu-system-arm version 5.2.50
(v5.2.0-1579-g99ae0cd90d).
