I did the print without GE, and they are evenly the same in all aspects, except when I was looking at it under my light source, the one without the coating was more like a mirror reflection image of my light, while the GE looked diffused in more areas. If you move the sheet around there are plenty angles and places where both have a mirror look. But looking at the same spot under the same angle it was diffused. Almost acting like an anti-glare. Otherwise 99.9% the same.
Having said this, I think once the sheet is mounted, it would be more apples to apples inspection, as the slightest difference made a splash of difference in comparing. I did lay them down, but they are not flat, so it made a difference.
*This is just my visual observation.
