Hmm, it seems the manufacturers were in a rush when they designed your
laptop! The bios version, logically, belongs in bios_version :-)

Could you attach the output of "cat /sys/class/dmi/id/*" and we'll try
and work around bios issues like this. Thanks.

I deliberately changed it, as the vendor is supposed to be the person
or company that designed or created the profile. In this sense, it
seemed wrong to say that the profile was created "by Lenovo" when it
was created by me, for my Lenovo display.

Hmm, I think the fields have to be displayable. We need to look at
adding private fields if we want to add any machine parsable data into
the ICC file.

I think the lookup is valuable as it works most of the time. Your
panel should have encoded SAM into the PNP field, not SEC, unless of
course the panel really is a Seiko panel that's been rebadged as a
Samsung. For what it's worth, my nice expensive LG panel is actually a
generic Goldstar chipset with LG additions and plastic wrapping.
Hence, it shows up as "Goldstar" as the vendor. :-(
