Deep blacks or shadow detail
Do you have to sacrifice some shadow detail to maintain relatively deep blacks? Is there a way to have close to max shadow detail and not have grayed blacks?

It depends on the TV. One of the best out there now is the Samsung B750 series. It has the UCP which holds the deep blacks and gives you depth inside those blacks which most TV's can't handle. You need a good grayscale, something that gradates and transistions properly giving you a more realistic looking black. Many TV's cannot do this properly and manifests itself by having blacks look like a glob of tar. The key for having deep blacks on an LCD is having LD LED or a CCFL (like the B750) with the UCP. The Dark Knight on the B750, when calibrated properly, combined with the UCP, is nothing short of spectacular.

UCP isn't always necessarily a helpful feature - look at the XBR8. No UCP and much better picture quality than the B750 no doubt. XBR8 seems to be much better than the 950 too.
UCP (Ultra Clear Panel) also calls for reflections. Reflections can be bothersome - and I hate UCP. Semi-Gloss all the way! YEAH

Things are quite complicated with LCD and plasma because of that “famous” specification: dynamic contrast ratio.
I can tell you one thing: 10 bit processing and 10 bit panel resolution will give you ridiculously small amount of dark area graduation levels. Maximum possible graduation number is only 1024 levels, and this has to be utilised from the darkest, up to the brightest levels. Depending on dynamic range that processing / screen can display, you may end-up with only 16 dark area graduation levels (!!!)
This applies to digital cameras processing and sensor dynamic range of 6 steps
If the TV is capable of very dark black, on one hand that is really good, but on the other - possible graduation levels will be shared between “wider” dynamic stop…
I found that the darker the blacks are, the less graduation I see.
Anyway, we should see gradual switch to 12 bit processing AND panel resolution, hopefully, which should give respectable results.
All “artificial” steps taken to make darkest areas really black will only do exactly that and nothing else – the fine shading can never be “re-generated”
