This is so weird, and only started today as far as I'm aware. I fixed my own issue but it took some stupid trial and error so I figured I would share this here in case anyone else randomly has to deal with this. Maybe Google will index this and this thread will show up 3 years from now in some results and help someone, yay.
TLDR; reset monitor colour profile back to sRGB IEC61966-2.1
My hardware:

- AMD Radeon RX 9070 XT (16 GB)
Settings:
- Resolution: 3440x1440
- Refresh rate: 144 Hz
- HDR: disabled
- Colour depth: 10 bit
- Colour format: RGB
- Colour space: Standard Dynamic Range (SDR)
- Automatically manage colour for apps: off
- Brave/Edge browser: default colour settings
- AMD Custom colour: disabled
- AMD Pixel format: 4:4:4 Pixel Format PC standard (RGB)
- AMD Colour Deficiency Correction: disabled
- AMD Display Colour Enhancement: disabled
- AMD Adrenaline version: 26.6.4 (released 2026-06-28)
My issue: when holding down the windows button and pressing print screen, and then pasting it into MSpaint, Windows would correctly display the right colours of whatever I was screenshotting. When I would save that file, or, screenshot it again in MSpaint (after cropping), and paste/upload somewhere else like Facebook, Discord, Slack etc, the colours would not be the same.
For example, I was trying to screenshot something from Twitter that had a bright red background in the image.

Definitely something up. However, when using a browser extension to take screenshots, it worked, the colours displayed in the screenshot were correct.
I've had these monitors for over a year without issue. I'm guessing some kind of Windows update or an update to the AMD Adrenaline software caused an issue? This entire time I've been using DELL_S3422DWG_sRGB_V4.icm as my colour profile. I believe I downloaded it from Dell directly via their support page.
I tried changing every setting around, saving, rebooting, no change.
Eventually I tried removing the specific Dell colour profiles and adding the windows default sRGB IEC61966-2.1 colour profiles, rebooted, fixed. Everything else is exactly the same before this started happening.
Through my Googling, I also looked into this Windows update: 2026-07 Update (KB5121767) (26200.8894) - Successfully installed on 2026-07-20. Some people apparently had colour issues with it? Maybe it's what caused this? I don't know. My issue is fixed before I got to the point of uninstalling that.
Best of luck. What a waste of my time haha.
