It's entirely possible to make an Au-Ra without the LED glow look in the new system, either by turning off limbal rings entirely or by making sure the base color and the limbal ring color are in a similar color family. Or making sure the base eye color is the same mid tone as the limbal ring.

The background eyes of au raw now have a gradient in the iris itself (old system didn't have enough detail for that to be possible.)

This is part of the reason they gave everybody a free fantasia.
