I need to find out what color spacing is best for the Epson pj.
You're making this more complicated this it has to be.
Yours is a 1080p projector, so the best things that you can expect from it is 8bit colour _ that is what's used on a standard Blu-ray.
RGB will give you your best blacks with out crushing and good bright areas.
You can experiment around with the other Chroma formats eg 4:2:0 or 4:2:2 or what's made available to you in the players menu, but I think you'll find that RGB is best.
4:2:0 will very often give you too deep of blacks for example.
There are video processors that can upscale the chroma, but it's so subtle that you have to do side x side comparison to see the difference.
A Blu-ray player isn't meant to upscale and give you better chroma, what you want to do is match what the disc is authored in and in most cases, that's RGB.
There is allot more to it then that, and someone else can chime in here if they want, but you may find that reading all about it will give quite a headache.
