Update after a few weeks of using my rs2000 for over 50 hours.
My bulb showed up yesterday, I sent the form in about 10 days ago... Completely unexpected. It's gonna suck to test it now because everything is dialed in perfectly and I'll have to move it to swap the bulb...
To date, no real issues with the rs2000. No yellowing (I have a big screen, so my iris is wide open on Auto2) even on scenes with all black and just a little bright white text. Not saying it can't happen, just that I haven't seen it and I won't purposefully go looking for flaws that I haven't noticed.
I might have seen a case where a few pixels clipped, but I didn't do any investigation when I saw it, and as far as I know it could have just been the way the movie was. I don't even remember which movie, might have been Captain America First Avenger in 4k.. But being ripped, it is totally possible it was an artifact from the file too, so I let it go. Again, no need to go looking for flaws if I'm not already seeing them.
During initial install, I made a 1 pixel adjustment to blue and red for convergence after about an hour of warming it up, but at ~24 hours I had to make some adjustments to how everything was mounted, and once I was done I went through the convergence again and both red and blue were off by exactly 1 pixel, so I zeroed both out again and it is dead on for 90% of the screen. I get a little misconvergence on the bottom left and right corners (one blue, one red) but we are talking a fraction of a pixel where the halo of the color is starting to peak through the white line on one edge. Very minimal and no need for zone convergence by any means. Bottom line, after ~20 hours the convergence ended up being near perfect with no adjustment. Kind of cool.
Bright corners still stand out on blackout scenes, but either I am getting used to it or it is calming down a bit. Still perhaps the worst thing about this projector, and given the overall quality of the image, it is an insignificant price to pay.
Here is my philosophy on what I should expect: Based on reviews, the closest thing to a "perfect" home projector is a mid-six-figure projector. Since I have no desire or ability to spend that much, I have to expect there are imperfections in anything I buy that is cheaper. Bright corners is a small price to pay for having exceptional quality in just about every other aspect of this projector, and all for a sub $10k price tag. Granted, even with the sales and pre-order discounts I was a bit over the $10k mark with the added Paladin lens, but I still feel like I found the sweet spot - the point at which there is no need to spend any more money on a projector setup. Everything I watch amazes me now, and I can't even come up with the words for how good 4k looks.
I've mentioned this before, but I had an e-shift Epson before this, and 4k content was already amazingly crisp and sharp, and with some adjustment to gamma curves and other settings, the color and brightness on HDR was spectacular and very pleasing, even on my rather large screen. I didn't upgrade for more resolution from the native 4k panels, nor did I upgrade for better contrast or even a better lens. I upgraded because my settings didn't fit all HDR content and I hated that I had to constantly tweak to get some movies to look better, and even then I just couldn't get everything to look good. I wanted adjustable tone mapping for all HDR sources and for it to be pretty much "set it and forget it". I also needed to get away from 10gbps HDMI, but just about any upgrade was going to give me 18gbps. I did expect small gains in just about every aspect of the projector, but I wasn't expecting anything revolutionary. The more I watch, the more impressed I am at the improvements across the board. EVERYTHING looks better with this projector, including 1080p content that is upscaled by the exact same sources I was using with the Epson. So I went from what I thought was "good enough" to being wow'd at every turn.
The most unexpected improvement is in the resolution. I simply didn't expect to see much of an improvement here, but I was wrong. I sit ~11 feet back from a 150" wide 2.39:1 screen, and there is absolutely no question in my mind that the extra 4 million pixels make a significant and totally noticeable improvement. My eyes are not the greatest, and I am projecting on a microperf screen, but nobody could convince me that I am not seeing a major improvement in resolution. I can't point out individual pixels on my screen from my seat, but I can certainly see more detail in both static images as well as regular video. I am not talking about the HDR improvements or the color improvements, although those are all there as well. Straight up, I can see more fine detail than I could with e-shift with all other things being equal.
Based on my personal observations on my particular setup, I would recommend this projector without hesitation. No caveats, no reservations, it is simply better than I would have expected and well worth the price.
IMHO, even if the issues some are noticing were more prominent to every viewer, I don't think there is a better option at this price point, and for some people I don't think they would be satisfied with anything less than the mid-six-figure option, so while their opinions are perfectly valid, if I were evaluating my options those would mostly be on the outside of the bell curve. Just my 2 cents.
