Hello,
I'm currently looking for a new display for gaming and photography and am currently favouring the LG 27GL850-B. However, I noticed it has a wider gamut, like many or most of the newer screens out there. While I'd say for photography this is a huge advantage at least for prints (please correct me if I'm wrong), most content out there is still available in sRGB which is also the standard for any content on the web.
I went down the rabbit-hole and even watched Taran's video on colour calibration (https://www.youtube.com/watch?v=QPubgoqtfbk).
I also learned that once activated even applications like firefox can do colour management. I own a Spyder 4 colorimeter so I can create a colour profile of the screen and add that as an icc profile to Windows/Linux.
Is my understanding correct that once I create such a colour profile for a wide gamut display and the application supports colour management (OS itself, Firefox, Lightroom,...) the colours of sRGB content will be transformed to the expected colour? So for sRGB content the application wouldn't show me colours outside the sRGB space, although my display is capable of doing that?
Assuming I'm correct so far, there's a second topic that grinds my gears a bit: gaming. From what I found games do or do not perform colour management. Some even come with their own colour profiles. I just assume it's an easy way for applications to perform changes to gamma settings, brightness, contrast,... However, this does also mean that games on a wide gamut display will inevitebly look oversaturated.
Inspired by Taran's approach I created a garbage colour profile for my current sRGB display (I calibrated it while setting the green channel to 0) that has an easily visible orange taint over it when applied to my otherwise default settings. I then started a few games from my Steam library:
CS:Go: Provides its own colour profile when in fullscreen mode. However, it uses the OS colours in windowed fullscreen
Arma 3: Provides its own colour profile when in fullscreen mode. However, it uses the OS colours in windowed fullscreen
Portal 2: Provides its own colour profile when in fullscreen mode. However, it uses the OS colours in windowed fullscreen
Lego Ninjago Movie: Provides its own colour profile when in fullscreen mode. No windowed fullscreen modef
Neon Drive: Uses the OS's colour profile
Rocket League: Uses the OS's colour profile
This certainly is a small sample size, but can I roughly expect most of my games to look like garbage if there's now windowed fullscreen mode? I know that many wide gamut displays come with en emulated sRGB mode, that, however, usually locks many of the display's settings, and changing the OSD all the time is also pretty annoying.
Is there a nicer method I overlooked to force applications without colour profile to be interpreted as sRGB and transformed correctly and for other applications not to assume my display is sRGB and to transform for my display instead?
I feel like with many to most newer displays coming out with wider-gamut this will become and increasing issue, even though many users feel that "the more vibrant colours are great" - they aren't exactly more vibrant they are likely just wrong. Likely the colourspace will get even bigger in the future, making these current games look even more off.
