I don't need to claim that I have a Voyage without any gradient, because I know I have one like that. I know this because my Oasis does have that gradient, although its only visible at higher than 11-12 light settings which is above how I use it. I never go above 8 in almost total dark and never above 12 in bright light.
I know what I have and I know I can see those things as I had a horrible PW1 and I know its there on the Oasis like I said. Its not on my Voyage. My Voyage is even and clean on all light levels, any light conditions. Those are the facts.
I cannot take pictures to save my life, so that isn't an option. Not only can I not take pictures that aren't blurry, I don't have a setup of a room where there wouldn't be light coming in from one side or another. Its just not something that is possible for me. I can't even take a pic of a squirrel without blurryness.

Not that I would play this game with some of you guys anyway. I know what the facts are and that is all that matters to me. And since I know what that stuff looks like, you can't use the silly stuff about me not being able to see those things.
So there is that.
