Everything is important to some degree. When I said ANSI is less important, I meant at high numbers.
That's obvious because you can just go look at a high ANSI projector and notice it doesn't help the contrast much, whereas a high Native projector does look more contrasty.
The best test for this is to compare 2 DLP's, one with very high ANSI and one with very low ANSI, don't compare an LCOS to a DLP, that comparison is biased in our eyes.
As you already know, the contrast is lost in ANSI whenever the black level is raised, this is because both black and white are projected on the ANSI pattern, unlike Native which is projecting full White, then full black.
So with Native, it's harder to pollute the number because when taking the second measurement, only all black on the screen (hence no light in the room).
With the ANSI pattern, you are measuring the black at the same time as the white.
The bigger the screen, the harder to contain the ANSI, generally speaking.
With ANSI contrast, it is almost like you ALWAYS have lights on in the room, because it's projecting the white squares next to black squares, the projector is self-polluting.
With ANSI it does not have to actually damage the contrast on the screen, just the room's absolute black level, so any reflections that raise the black level will damage the contrast.
The only way the above would NOT be true, is if you had a checker boarded shirt that reflected light at the screen with pinpoint accuracy to match the White/Black squares at EXACTLY the correct positioning.
