Thank you for your helpful response which caused me to go do some digging. I now realize that my questions weren't put correctly, judging by the response.
Again, I don't see how the browser is pertinent. Converting to sRGB could be! Your browser is either color managed or it's not.
I'm glad at least that it's that simple and answers my title question. From that I now understand that
if a browser is color managed it will accept and display an image with a V4 embedded profile correctly. Thank you.
And what other's see? Huge crap shoot.
Yes, that is well understood by most, even me.
So you can try converting to sRGB with the sRGB profile that has a perceptual table, but it's not going to solve a lot of the issues with sRGB in general, it's just one extra option.
I do not wish to solve all the issues with sRGB and, here, I'm trying to concentrate one subject. Further reading suggests to me that, by using "sRGB", I have confused the issue. What I am still looking for is a V2 display class profile that has the six tables and is similar enough to sRGB e.g. same or similar primaries, white point, black point, illuminant, blah-di-blah.
Same question as in the OP:
Does anybody here know of one? If so, please post a link.
Soft proof, try both tables, pick the one that looks best
Picking "the one that looks best" was not my intent but I think I get what you mean.
(they may both look like crap).
LOL. With my shooting skills, very likely.
