Shadow detail is a tricky thing, and people often get into arguments when I mention it (Although this thread people don't argue as much anymore, strangely enough). I think this thread is calmer now because all of us in here pretty much agree, that the hc4000 produces a stupidly amazing image for the price.
That said, shadow detail is mainly a combination of NATIVE contrast and gamma. The other potential issues affecting shadow detail are the processing algorithms (image noise reduction, banding, etc...). That can either detract, add to, or ruin shadow detail in dark scenes (or turn it into blobs). I would argue that even though DLP produces less gradiated ranges in the darkest of dark scenes, it still produces a slightly cleaner scene than some LCOS, but the LCOS will still cream it in dark scenes, there is just no way of getting around that.
Given the JVC RS-45 has much higher native contrast, after you calibrate the GAMMA the dark scenes should look better across the board, this includes shadow detail. That doesn't necessarily mean in most scenes you will SEE MORE DETAIL than a Mits hc4000, what it really means is that the detail will in essence appear more vibrant and delineated, so our brain registers it better. The detail will be less clumped together compared to a projector with less native contrast.
There is no question that if dark scenes is your end-game, the JVC is worth a try-out, but I do worry about the lamp issues. I mean I can put 3000 hours on a projector in one year because I leave it on while on my computer (I work from home half the time in my job), so I can really burn lamps fast. That could cost me $2,000+ per year if these lamps start failing too often. After 3 years, I could have bought a $5,000 projector using different lamps, so that is a bit odd.
That assumes the JVC still has the lamp reliability problems, no-one knows just yet, but it does worry me severely.
