--- Comment #21 from shashank.sharma at intel.com <shashank.sharma at intel.com> ---
I can see in intel_hdmi_deep_color_possible() that we are allowing 10bpc only
for GEN11(ICL) onwards.

if (bpc == 10 && INTEL_GEN(dev_priv) < 11)
                return false;
This means we can't (legally) check 10bpc on GLK.

I am suspecting that this Samsung monitor is expecting something different in
it's UHD deep color mode, coz I am not able to reproduce this issue with any of
the UHD/HDR monitors available with me (LG, Philips). Unfortunately, this issue
can't be worked upon without this particular monitor.
