I think the variations are intentional. If I were a designer and looking to match backgrounds, I wouldn't eyeball it. I'd screenshot the target and eyedropper the color - that's independent of panel differences. But maybe I'm old fashioned and not a designer anyway. "Dark themes" are the new sexy right now and everyone's having a play at making their design palette stand out. I think good usability is taking a back seat to artistic freedom and expression.
