I’ve recently turned on the Firefox color management fulltime for a week. I noticed that apart from most images looking less saturated, which should be accurate, the Tone is also much lighter. Alot of websites/ images seem to pick up quicker from black which overall looks to have much less depth.
Now, if creators are targeting a mainly uncalibrated audience, whose monitors are not even using srgb tone curve, rather the 2.2 relative.
Is it more -correct_ towards artist intent- on the consumer end to NOT use ICC to web browse ?
A way to do what you ask is a synthetic profile as display profile but do not install it as default display profile in OS, configure it in firefox about:config display profile.
Such synth profile would have typical matrix-like info with your display primaries for gamut correction and sRGB TRC.
This has a collateral effect of darkening AdobeRGB JPG in black side, but they are uncommon in web contents
I would let firefox with it’s full color management, without this tweak… but you asked for one.
