Tell me more about how, "There is -no possible way- for an image that was actually developed or converted as a sRGB file to then include out of gamut colors for sRGB…"

Since you asked . . . .

It's a great technical article from PP Magazine on the color gamut Lightroom employs in the develop module. The article dates from Lightroom's introduction, so the author is out-of-date when he mentions the lack of soft proofing--we've now got that feature.

However, it turns out I'm right that Lightroom uses ProPhoto RGB to render your RAW data in the develop module, and that you can't change this. Well . . . let me be more precise: Lightroom uses a gamut that's a spitting image of ProPhoto RGB with just a few small tweaks. Adobe apparently called it "Melissa RGB" and "LoveChild RGB" internally.

Anywho, what this means is that your test never actually developed files in sRGB (or AdobeRGB). You developed in ProPhotoRGB (well . . . "LoveChild RGB") and then converted that articulation (via relative colorimetric conversion) to sRGB and AdobeRGB when you outputted your results. You never actually saw a native sRGB or AdobeRGB articulation of your RAW.

Yay, we've cleared it up!
