LR classic does not seem to respect display color profiles as assigned in Windows 10 colour settings

LR classic does not seem to respect display color profiles as assigned in Wndows 10 colour settings.

I have two different calibrated screens (Left: HP, Right: ASUS)
I want to make sure that the color profiles assigned by windows are used by
- Lightroom Classic
- Photoshop

To test this, I did the following:
- Assign a yellowish profile to the left  display (vcgt_cm_test_yellowish_blueish.icc)
- Assign a reddish   profile to the right display (vcgt_cm_test_reddish_cyanish.icc)

As reference I opened the attached image "PDI Test Image.jpg" (with AbodeRGB as embedded profile) in IrfanView, which is perfectly supporting display profiles.

Expected:
- Image is shown on the left screen
-- in IrfanView as yellowish
-- in Lightroom Classic as yellowish
-- in Photoshop as yellowish
- Image is shown on the right screen
-- in IrfanView as reddish
-- in Lightroom Classic as reddish
-- in Photoshop as reddish

Actual:
- Image is shown on the left screen
-- in IrfanView as yellowish  --> OK
-- in Lightroom Classic sometimes yellowish (would be OK), but mostly neutral (NOT-OK)
-- in Photoshop sometimes yellowish (would be OK), but mostly neutral (NOT-OK)
- Image is shown on the right screen
-- in IrfanView as reddish  --> OK
-- in Lightroom Classic sometimes reddish (would be OK), but mostly neutral (NOT-OK)
-- in Photoshop sometimes reddish (would be OK), but mostly neutral (NOT-OK)

To illustrate this, I created a small video of both screens:
https://www.dropbox.com/s/9th4b57txvz0i3k/Du2a4977-1.m4v

All files involved can be found here:

Does anybody know what to do to make LR Classic and Photoshop use the display color profiles as defined by windows?
Or do we have a bug in LR and Photoshop here?

Both LR & PS seem to be doing the same thing - apply the image's colour profile, not the monitor profile. Which is surely correct unless you assign the monitor profile to the image. I see what you mean though. What is the point in profiling your screens?

Hi Brian,

thanks for the extremely quick answer ;)

I want to make sure that my calibrated display profiles are used (e.g. "HP LP2475w 6500K Gamma 2_2 - 20.07.2019_1.icc")
The display profiles have been generated using my xrite i1Pro.
My assumption: if the reddish/yellowish profiles are ignored, my calibrated profile ("HP LP2475w 6500K Gamma 2_2 - 20.07.2019_1.icc") will also be ignored by LR/PS.
This would mean for me: Wrong colors.

What you are overlooking is that both LR & PS load the Windows system assigned display profile during launch. If you change the display profile or drag the display window to a monitor using a different display profile you need to close and reopen LR & PS so it can load the new profile. In addition the yellowish and reddish display profiles may be incompatible with LR & PS. How were they created?

InfranView apparently monitors and uses the system display profile file path directly. So profile changes are reflected real-time. As mentioned LR & PA apps only load the system display profile during launch. This is probably due to coding complexities that would be required to monitor and change it real-time. Looking at your video it appears the system display profile is being used properly by LR & PS. What specific display models and graphics card are you using?

As I am a Macintosh user myself I cannot comment on what you see exactly, but I can assure you that both Lightroom and Photoshop do use your monitor profile(s) and there is no option that you need to check for that to happen. There are a few issues with certain profile types however, so that may be what is going wrong here. Do not create V4 profiles for example, stick to V2 profiles.

As you can see in the video, I restarted LR and PS. After restart they both had the IMHO wrong colors (neutral instead of yellowish/reddish).
If you change the display profile or drag the display window to a monitor using a different display profile you need to close and reopen LR & PS
I would like to use LR with the same picture on both screens (secondary display).
I expect this should be possible.
What specific display models and graphics card are you using?
screen on the left: HP LP2475w
screen on the right: Asus PA329C
Graphic Card: NVIDIA GeForce GTX 750
In addition the yellowish and reddish display profiles may be incompatible with LR & PS. How were they created?
The yellowish/reddish profiles are testing profiles taken from https://displaycal.net/
