The Dark Iron Dwarf and Lightforge Draenei have baked in textures around the eye socket that are an indication of their respective Yellow and Fiery eye glows.
However these textures are not edited/updated for the new DK BLUE eyes.
Evidence:
On the Lightforge Draenei, you can make out this yellow blur surrounding the eye, and on the Dark Iron Dwarf you can clearly see the dark red to illuminate the eye socket.

Lightforge:
Now the Death Knights on PTR
Dark Iron:
Lightforge:
One can clearly make out the off-tint surrounding glows in the DK specimens. While passable as "edgy/bloody" on the Dark Iron, the Lightforge's yellow tint looks entirely like a glitch.
The Worgen however, recently updated, do NOT have this problem. As seen here.
Worgen Red Eye Glow:
SAME FACE Worgen Death Knight:
No red to be seen on the DK iteration, and this is an example of a well executed texturing.
I hope the Dark Iron's and Lightforge are fixed, because it's not a stylistic choice. This is an oversight.
I downloaded PTR again just to post about this so don't let us down
Love you Blizzard!
Spread the word somehow folks. Should we tweet? This kinda stuff shouldn't make it in. Posted on official forums too
