Windows Workflow videos
 
In addition to the regular tutorials, we've also got some workflow videos shot on the Windows version of Photo that cover using a variety of features to edit an image to completion. These tend to be released on a more informal basis.

RGB pic to CMYK doc of Photshop = same color as it was in RGB mode.
RGB pic to CMYK doc of AP = different color. Mostly negative.
I've tried to search for answer and I know that someone talk about gamut, color space, color profile, color proof, etc.
But frankly with my stupidity I don't know why Photoshop can maintain the same saturation, brightness, etc, while AP can't do so. I'm not educated in digital arts enough and this really bother me for a big while. Can someone tell me the answer so I can sleep well from now on? Is it possible to have AP act like photoshop when import RGB file into CMYK doc? Thanks a real million!

I would check...
- If it is the same exact image. Some images have tones that wont get out of CMYK spectrum (ie, you don't have certain intensive greens, etc). 
- What CMYK profiles are you using to convert too. It can vary quite from one to another, between two CMYK color profiles.
- In what way are you converting (relative, absolute, perceptual, etc) This alone can make a world of difference, just like other settings applied in the exact moment of conversion.
- In what color space was the image originally... Adobe RGB? sRGB ? it can also introduce variance.
- If you could upload the photo, if there's no copyright issues or etc to upload for helping here, then someone with Photo could help you find the issue.
Also, telling us to which exact CMYK color profile would you want to convert the image to.
I am not offering for that help, as I don't have Photo.... 
Edit: And that you are trying to convert from a specific RGB color profile, to a specific CMYK color profile, and is the same situation in AP.
 

Thanks SrPx. My CMYK profile is SWOP v2 (both PS and AP)
 
The first one is original sRGB from DAZ Studio
 

 
The second one is the result of importing to new CMYK doc of Photoshop. The result is almost exactly the same to the original.
 

 
The third one is imported into new CMYK doc of AP

 
As you may notice, red level is dropped dramatically. Sometimes it's good. But most of the time I have to abandon AP because it takes too much time to adjust the color alone (I'm not such a professional and editing color is not my beloved job).

To add a point of view. I suspect that now I have a stupid workflow. I import original pic to new CMYK doc of Photoshop. Then I open the saved psd file with Affinity Photo. I apply the AP's features I like. Then export to psd again for easiness of final procedure in Indesign. I just want to know a way to do it alone in AP. I know that nothing wrong with gamut since I can import CMYK psd file with no flaw. Just don't know how to import original file into AP without color problem. Thank you!
