If you have an up to date Win 7 64bit, PS CS6 or CC, and calibrate your display with any colorimeter spectrophotometer and their respective softwares.

Google this image and download it:
hd_high_resolution_flowers_wallpapers-1920x1080

And be sure to has this Color Settings setup:

Working Spaces:

RGB - Adobe RGB 1998
CMYK - Cotade FOgra27 (ISO 12647-2:2004)
Gray: Dot gain 20%
Spot: DOt Gain 20%

COlor management policies

RGB CMYK and GRAY
set: Preserve Embedded Profiles

mark: Ask when Opening / Ask when Opening / Ask When Pasting

Engine: Adobe (ACE)
Intent: Relative Colorimetric
Mark Use Black Point Compensation
Use Dither
Compensate for Scene-refered Profiles

mark too only: Blend Text Colors Using Gamma 1.45


Open this file, convert to CMYK and hit the F key to toggle between screen modes.
If you have a calibrated display with, let me say, Eyeone and Coloreyes, and the videoLuts loader is on, when you hit the "F" key, the colors on the CMYK image, will become way more saturated/heavy/dense than you first open the image, so Hit the F key until the screen mode is "normal" and the color come back to the normal too.
I test this behavior in 8 machines so far, and in all this machines, the change in the colors are very noticiable, to reach a point that I cant be used in color professional works.

My setup:
- Photoshop CS6/CC
- Win 7 Ultimate 64 bits English with all the updates.
- ATI 7870 / HD 550 and early graphics cards.
- Dell U3014, CINTIQ 21UX (in the 7870), 2 samsung 2232 in the 5500 (all on, or one at the time)
- Spyder 3/4 Elite, Eyeone Display 2, DispCal (argyll), ColorEyes 1.60


ps: the loaders startups of each display calibration software, was choosed one at a time, when I restart the PC (so, there are no multi loaders trying to put your luts at same time)

- PS CS6 / CC and WINDOWS are totally up to date
- The driver of display cards, are the latest AND the windows certificated

- There are no other software installed on the PC that try to handle the display card or even diferents CMS.
- In fact the Windows is a fresh install

Let me know if I could express my self good enough.
Regards,

Is there a question here ?
Are you trying to ask why cmyk colors aren't displaying correctly on your monitor?
A monitor only displays accurate color in the RGB space, if you try to display CMYK colors on your monitor, it is displaying a conversion it is making and the colors cannot be completely accurate. Your better off to create your work in all RGB and let the printer make the conversion. I think this is what your after. No?

I'm sorry but,
Did you really try to do what I describe?
My "ask" would be if Somebody could confirm or deny the changes of *CMYK* colors when you hit the "F" key and toggle the acerem mode..., this was suposed NOT work in that way.
And even, if have some fix or people are aware of this.


And what your claim about "only RGB color are displayed correctly", is simply WRONG.
The color mode (RGB/CMYK/LAB) doesnt dictate how much right or wrong any color is displayed to user, but instead, how well their color managed workflow is used.
Anyway, thanks for trying to help.
 
Sorry. Maybe someone else can help you. Maybe I don't know how to read English. So, your asking someone to go and change their PS setup and run a test for you..right?
 
You are correct that the F key should not change the appearance of colors on your display. It does not do this for me.

However as ALB correctly implied, it's very unlikely that you will find anyone who will be willing to change their settings to match the extensive list of settings u gave for your system. Instead, I suggest that you search the Internet for anomalies associated with the F key. For example in a few seconds of searching, I turned up the following complaint:

Good luck,

Tom

PS - Also, as ALB indirectly suggested, I too would suggest that you state your problem and your request more concisely and at the beginning of a new thread instead of immediately launching into that long list of settings and system configuration specs. It sounds too much like a pointless, overly detailed demand the way it is currently written.
