Yes. I stand by what I said. The visual color gamut of a screen (wide gamut or not) is much larger than what can be accurately reproduced by traditional CMYK printing. Period. While it is true that the monitor cyan slightly exceeds the CMYK color space, you are ignoring the elephant in the room, the rest of the color gamut that cannot be reproduced at all with the additive processes of putting ink to paper (those would be the vast grey areas in the screenshot comparing a generic RGB to a generic CMYK profile). Even converting from sRGB to CMYK cause a substantial loss in color fidelity, especially in the blues. Hardware calibration is the only way to achieve reliable on screen results, so that what appears on the screen matches a "press proof".
Without debating the minute intricacies of color spaces, and color profiles (which most large printers & prepress houses strip out anyway), the basic premise is that RGB technologies display a much larger color gamut than what can be reproduced in the narrow and limited gamut of CMYK.

Most importantly I don't know of ANY screen out of the box that will match, Apple or not, wide gamut or not. EVERY single printer I have ever worked with will strongly recommend both monitor calibration, and more specifically calibration through the use of an external calibration device.
I don't claim that the glossies are more accurate, or not. Regarding reflections there are none in my working environment, ambient light is reduced, lights are kept very low, and I use shades when working on anything critical. Much as any imaging professional would do...
