Colour shift between LR and Microsoft Photos? Feb 11, 2019 20:27:14 GMT

We are not forgetting the issue.
I must say that the way Microsoft manages colours in Photos and Windows Viewers is still mysterious for me, even after spending some time to understand what is said about it in the Internet and by testing by myself and checking profiles in the files themselves (exif tool).
What I can say from your Windows screenshots is that you have the default settings, which should be ok. I had found a tutorial in French about the best settings... which I can no longer find now!
The advice was this setting:
We all agree that the files exported from LR and reimported are fully recognized, no information about the color profile is lost.
Sepiana and myself find that Photos shows a correct (if not strictly identical) look of the Prophoto file. Nothing like the discoulored result from non colour-managed browsers in this case.
You find a distinct colour shift from yellow to red (is it also more saturation?)
Why would Photos show differently in your computer than with ours?
My first question is to check the LR option in the export: was it exported in ProPhoto or aRGB, sRGB? It's easy to check the profile when opening the file in PSE, PS or LR. With properly tagged Prophoto, no issue in Photos for us.
I was wondering about the lack of calibration in your case. You are right it should not explain the difference between LR and Photos. For further tests, I have used PS which offers many more options than PSE to convert or assign profiles. For instance this test: conversion of the prophoto test image to aRGB - remove profile - assign aRGB or my monitor profile: no visible colour shift, even if my monitor is not wide gamut. Tip: we can work with the test file by Andrew Rodney:
In my experience, the only situation in which I find a very significant oversaturation in conversions/assignment from an original ProPhoto is when: it has been converted to another space like aRGB, Display or sRGB and then assigned a ProPhoto profile. That is equivalent to applying the conversion twice.
To summarize: we could work on the same test ProPhoto file,
we need to be sure what profile is embedded (tagged) into your resulting LR export.
