Images are dull in PS (2024) after I export them from LR Classic. I am using ProPhoto RGB in both

First of all, color settings in Lr and PS don't need to match. You can set any color space in Lightroom External Editing. Whatever profile you set will be correctly treated in Photoshop. The whole point of color management is that colors are preserved when moving from one color space to another.

I would not recommend ProPhoto until you have a lot of experience and understand the implications. ProPhoto is very risky and will mercilessly exaggerate any problems.

In Photoshop the working space isn't important. The embedded profile will override it. In Color Settings, the only really important setting is "Policies". This should always be set to "Preserve Embedded Profiles". That's the default, don't change it. If you have, change it back. It means that any color profile coming from Lightroom will be preserved, and override the working space.

Any difference between two color managed applications, whatever the embedded profile is, means that the color management chain is breaking somewhere. The color management chain has three links:

• the embedded document profile
• a valid monitor profile set up at system level
• a color managed application that will correctly convert from one into the other, and send those corrected values to screen.

The usual suspect is the monitor profile. It has only one job: to accurately describe the behavior of the display in its

current state. The monitor profile is a map, and like any map it has to describe the actual terrain. The optimal monitor profile is one made by a calibrator, based on measuring the display. Without a calibrator, you may get generic manufacturer profiles distributed through Windows Update. These profiles are surprisingly often defective in various ways.

A monitor profile is more complex than most people think, and if it isn't written to correct icc specification, applications may react differently. It may work in one, but fail in another.

This is why a difference is often an indication of a defective monitor profile. The conversion into the monitor profile is executed in the GPU nowadays, so you may also see a difference with GPU on or off. Same thing.

All of which is for background. If you post a side by side screenshot, it will be easier to tell where the problem is in this case.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
