I just replaced my w1070 with UHD51a.
My w1070 authentic replacement bulb had about 1000 hours on it. I have a 110" 1.0 high contrast grey screen.
While I don't have the equipment to provide metrics, and just from personal observation, there is no category in which the UHD51a is a downgrade from the w1070. Contrast, blacks, are at least as good, and to my eye, better. Particularly color, which is much deeper and more realistic when compared to w1070.
The UHD51a is noticeably brighter than w1070, including 3D. IMO, 3D is far more adjustable and immersive than with w1070; a big step up.
As others have suggested, 4K HDR is where the UHD51a really shines. There is no comparison with w1070, it's in a completely different league.
I use a Roku Ultra, and 4K HDR on the UHD51a has more than met my expectations in terms of resolution, color, brightness, contrast, etc. Netflix, Prime, Plex are jaw-dropping. Even lowly non-4K Hulu seems better. So far, I have only been able to get my Roku to work 8 bit 4:2:2 at 2160p @60 HDR. I believe Wesley said Roku would work with 10 bit 4:2:0, but I can't figure out how to make that happen and I don't know if the difference would be noticeable. (Westly, what Roku settings did you use to get the projector to work at !0-bit 4:2:0 2160p @60 HDR? When I tried 4:2:0 on Roku, UHD51a wouldn't recognize the signal.) I can only imagine what the picture will look like when someone releases a streaming device that offers all my required services (Netflix, Prime, Hulu, and Plex) at 12-bit 4:2:0 at 2160p @60 HDR!
The w1070 is far more plug-n-play than the UHD51a. There are many settings on the UHD51a that just don't exist on the w1070, so expect to go through a much greater learning curve. As others have mentioned, there are still a number of OS glitches with the UHD51a, so expect to encounter frustrations along the way.
Regarding Echo, once you go through the ridiculously convoluted setup process (when compared to other Echo devices), it works just fine, with the exception of turning on the projector. I have the power settings exactly as Optoma indicated, but I always get, "sorry, projector is not responding" when I try to use Echo to turn the UHD51a on. Once I turn it on via remote, all other Echo commands work as expected.
If you hang the UHD51a from your existing w1070 ceiling mount, the image will be several inches smaller than w1070. I will have to move my mount back about 3-4 inches to get it to fill my existing 110" inch screen. No other ceiling mount adjustments were necessary to get perfect alignment. I did use the UHD51a vertical shift to get it to fit the screen. Sometimes the light border bothers me, mostly, I forget about it. But I will install a velvet covered border to eliminate the issue.
