Photoshop Proof Colors: sRGB vs Monitor

[jerryl63992203]

If I work on an sRGB image in Photoshop and correctly tag and save it as sRGB, when that image is opened in a web browser should it look the same as in Photoshop's "Proof Colors: sRGB"?

In my setup, In Photoshop, shadows are lighter when proffed in sRGB, darker in Monitor_11_20_2021.icc. Images are also dark in Chrome, Firefox, Opera and Edge.

Photoshop's display only matches the browser display when Proof Colors is set to Monitor. But I read that proof colors is for printing and when Monitor is selected it turns off color management?

Here's what I'm struggling with conceptually:

Photosho's working space is set to sRGB.
The image is correctly tagged and saved as sRGB.
The file numbers that define colors are set by the profile.
The CMS converts the definition of the colors from Photoshop's sRGB via the monitor profile so they display the same on the monitor.

Then why doesn't the monitor profile make Photoshop's sRGB proof the same as what an sRGB-supported application (like a web browser) displays?

Here's my setup:

Calibrate Monitor with Pantone/Gretagmacbeth i1 hardware calibrator
Using Eye-One Match 3 v3.6.2 software.
Run calibration routine and a color space profile called Monitor_11_20_2021.icc is created.

Windows is set to the Monitor_11_20_2021.icc profile as default and Photoshop to sRGB IEC61966.21 as the working space.

I am embedding the sRGB IEC61966.21 profile in the image when it is saved.

Photoshop 23.0.1
Color settings working space: sRGB IEC61966.21

Windows 10 20H2 build 19042.1348
Dell U2713HM Monitor
Windows > System > Settings > Display : Monitor_11_20_2021.icc
Windows > Color Management : Device: 1. Generic PnP Monitor - NVIDIA GeForce GTX 745
Use my settings for this decive - Checked on
Profiles associated with this device: Monitor_11_20_2021.icc (default)

That's right. They should all match Photoshop. If they don't, something's wrong, and somewhere there is a break in the standard color management chain.

I don't use Chrome and don't have any experience with it - but based on what we have seen here in the forum for a while, Chrome's color management is frequently broken and apparently quite buggy. Edge, by the way, is based on the same engine and possibly susceptible to the same bugs.

I just know how it's supposed to work when everything is in order.

Firefox has been very reliable here. Set to mode 1 it will color manage everything correctly, including graphics and page elements, not just untagged images. If you have a wide gamut monitor (as I have), any color management problems will immediately jump in your face. I have never seen any mismatch with Photoshop.

As I said at the very beginning, proofing to Monitor RGB in Photoshop turns off color management. So again, that's how it will look when color management doesn't work. Any browser that matches that, isn't working as it should.

Between my brain, my eyes, the display, the types of display illumination, whether it wide-gamut, or HD, the drivers, the calibration hardware, the calibration software, the execution of calibration software, created calibration profiles, Windows settings, color spaces, color space profiles, the applications, the implementation of the CMS in the application, consumers with non-current browsers, users with who-knows what uncalibrated monitors, a myriad of rabbit-hole other things, and my own user error, I guess it's not too surprising that the CMS doesn't work in my system. 

Unfortunately, using Firefox is kind-of a fool-yourself solution. Because while it may work wonderfully on your system, hardly anyone is using Firefox. Chrome has a 65% market share, with Safari at 18%, and all the others at about 4% or less each.

There are unfortuently too many variables to to why colors may not match precisely. Although you have handled things correctly in tagging your file as sRGB, you need to consider that the website and browser may not be color managed.

here's a good way to test:
