gimp 2.10.32 rgb / cmyk

I had a feeling that it might cause confusion. Recommend uninstalling and getting XnViewMP

In the meantime, a bit experimenting on why the rgb2cmyk.org image is different from the cyan version. I still do not know the reason but comparing the conversions from the web / Gimp Cyan / Krita rgb converted to CMYK and as an afterthought actual Adobe PS. The web version has much more black (K) than the others. I do not know which is correct but the web is outnumbered 3:1

Rather a long image https://i.imgur.com/71r76kD.jpg  It all becomes "In the eye of the beholder"

Thank you for your answer. I thought you would give up on me after my last message as you must have guessed I am not technically proficient...
But I am stubborn!

Since my last message I have downloaded an image in CYAN via GIMP.
Last time, I hadn't OPENED the image so the conversion didn't work! But this time I DID!
I found out 2 things:
1) Even though i enter the RGB (Abode RGB 1998) input and CMYK (SWOP2006) output, If I leave the GRAY window at the bottom on "Select" the image can't get dowloaded into CYAN as a message tells you:
                                                               "Please set the default color profiles before loading images"

So I have to enter the GRAY window with either one of the 3 options: (it actually doesn't affect whatsoever the result of the CMYK conversion as I tried the 3 options)
EPSON Gray - Gamma 1.8
EPSON Gray - Gamma 2.2
ISO Coated v2 - GREY 1c - (built-in)

So I have 3 CMYK converted images exactly the same but different from my RGB2CMYK.ORG one.

So it looks as if if I am to use CYAN with GIMP, to convert my images into CMYK I'm going to have to slightly change my RGB image before converting so I get a satisfying result.

Since I am working on a book this RGB/CMYK business is all new to me!!!... More complex than I thought!
