Black diamond 1.4 vs slate 0.8

My projector is epson 5040ub and I was looking for a reputed ALR. After gathering resources I finalized the slate 0.8 fixed 5 133” CinemaScope. While I was trying to iron out the logistics and payment, I got another offer. I got a clearance offer for the same sized black diamond 1.4 fixed 7 for about $350 more than slate. When I entered the research and market I always found the black diamond to be financially beyond my reach despite it being on the wishlist. The place where I live I don’t have any big magnolias or thereabouts to go and have a look. Obviously I’m getting the black diamond at a dream price.
I just want opinions on which 1 you would pick and why and maybe help me make up my mind. Apart from SI, I can only get Screen Research and Elite screens at my location. While I guess elite is complete BS, Screen research is costing me about double of slate 0.8.

The 0.8 is going to have a little better blacks. The 1.4 is going to sparkle more and be a lot brighter. My friend has a 1.4 and for the guy sitting in the center, it looks really good but sparkles are noticeable if that bothers you. This is definitely a screen you'd only own if your "theater" is a normal room such as a living room.

I just bought this screen a couple weeks. It’s absolutely beautiful. Can’t go wrong.

Do the black diamond .8 screens have much sparkle to them in a dark room or a room with a low light?

Oddly enough on the SI "screen material wizard" they show that the higher gain versions provide a higher "system contrast ratio" than the lower gain versions

I know this post comes after a long time, but I went with the 133 BD 1.4 and it’s absolutely gorgeous. I’d recommend a 1.4 to anyone who’s planning to use it for HDR content. I self calibrated my projector using CALMAN disc and naked eye sight to set it up and it’s superb. I’m not claiming a 100% color accuracy, but hey, if it looks good to me, I’m happy. Somehow any number of pics I click or vids I make always make it appear duller than it is irl, maybe it’s just the way my cellphone camera is.

What about when you watch it in a dark room? I've heard it can be overly bright. Does it ever reject any of the light from the projector near the bottom?

So fast forward now, when you have an epson 5040ub married to a BD, I think it’s a marriage made in heaven. I’ve now jumped onto HDR content and with the right settings everything can appear picture perfect. Also from other places I picked, black diamond is better at vertical light rejection (floor and ceilings) whereas the slate is better at light rejections from the side. I personally kinda went off axis to test the black diamond is picky about the height with maybe a 30degree done (eyeballing it). Not to say they don’t work in the other axis, but one is stronger than the other. If I switch on the can lamps about 3 feet from the pj I need to go really bright to watch sports etc, movies with dark scenes are unwatchable. I still haven’t tried bright cinema mode with max brightness coz once the blacks ain’t there there is not much to watch. But I’m happy to report that with can lights about 8 feet from the screen is what we use when I’m watching sports with my friends in the room. Movies are watchable but a few darker details are blown out. I can watch it but I wouldn’t watch it kinda scenario. When I’m sitting with a 13 foot can light on, it’s almost perfect picture quality. 22 feet cans don’t affect it at all. Reflection onto the ceiling and floor are greatly removed. The walls do get lit but again not something that disturbs me a lot.

So with that said, I’d say if your projector is throwing the light off axis beyond the lens shift capability of your projector (easy check to know is if you’re using keystoning) then it might be a problem. As far as I can tell, I’ve got no issues of hotspots, sparkles (15 foot viewing distance) or over bright images.

I do use 5-6 different video memories for my day like Day time 16:9, day time 2.35:1, day time hdr, all the corresponding dark room settings. Like to keep the sports a bit brighter coz generally it’s with lights on and lot of people are used to ultra bright leds these days.

Image 1 is with the curtains open. The curtain you see is at the back of the screen. Points to note, projector can't project black light, so it'll only get as dark as your screen is
Image 2 is with the curtains drawn and the 4 front top can lights turned on. For brighter pictures it's fine.
Image 3 is the seating area cans (4 of them) turned on. I could lower the brightness color and contrast to get a better image. This is generally how I generally watch sports.
Image 4 is the trailer of Dark Knight in the tunnel. With the curtains open noting is visible, no matter what I do (side ALR isn't the best!!!)
Image 5 is the front top cans switched on. While certain details have returned, it's still unwatchable.
Image 6 is the rear 4 cans on. Image and movie is watchable but i wouldn't prefer it.

Hope it helps. Though to begin with, since I'm in a rental all walls are not the colors that I'd want, but what I have.
Can this screen do better? Yes.
Would I rebuy it now that I know what it's capable of? Yes
I had a locally made grey screen installed before this and this is so much better at the contrast. If I put a white paper on even a white part of the image, it completely disappears.
I think the videos of black diamond I've seen on YouTube are a little excessive and probably using laser projector, but there is one from that home theater dude, which puts a home projector on a black diamond. I think that'll be a good point to start.

Bhootz, Thanks so much for those pics. Very much appreciated. The screen does not look bad, and my environment has even more lighting control so I think I'll get a pretty great result.
