Seeking a Display Class ICC Profile with CLUTs

[xpatUSA]

Quite a rare beast, apparently.

I shoot flowers. Although most colors captured are in-gamut for ProPhoto (Kodak ROMM), saving as sRGB and thereby embedding the standard ICC V2 profile in the saved image causes some colors to go out of gamut with resulting false colors and saturation-clipping, unfortunately. Please, I'm neither looking for education as to why that is, nor dissertations on how to prevent that - other than via the subject of this thread.

I want to use true Perceptual Rendering Intent for viewing on my monitor and for posting on-line (not as 'save for the web'). Please see here for what I mean by that.

I have encountered two problems:

1) ICC does have the kind of profile that I seek. Unfortunately, it is their version 4 (V4) profile which is not acknowledge by either FireFox or Chrome in their default settings. I do not expect folks to adjust their browser settings to match my images, so V4 is out, even though it works with my editor RawTherapee (RT).

2) I found one profile that almost matches the description. "Whoopee", I went. Sadly, it crashes RT when I try to save an image with it selected as the output profile. On my Adobe-free computer, that is not good and, by the same token, telling me what LR or PS or CS does won't help me much - sorry.

I've been talking to the designer of ArgyllCMS, Graeme Gill. He kindly provided a brief description of how to create the profile I'm looking for but that would be heavy going for me, having never used his stuff.

So, finally:

question a) does anyone here use Argyll and have the ability to create profiles from scratch?

Question b) does anyone know of a Display Class ICC Profile with CLUTs, other than one called ppRGB_sRGB.icc ?

Thanks for looking!

Sounds like a question for Andrew Rodney. He's here from time to time, but LuLa might be a better bet.

Thanks, Jim. I've already posted there and he has responded but not too helpfully I'm afraid.

Thanks to all who looked. After consultation with a RawTherapee developer, the profile didn't work but only for saving as TIFF, which was I was testing with. Turns out that RT does not crash when I save as JPEG. Which is what I was going to use it for, so all is well :-D
