Red Hat Is Hiring So Linux Can Finally Have Good HDR Display Support

[Sonadow]

You're hallucinating. Chrome under Linux doesn't support anything but 8bit output.

Here's how it's "running" at "DefaultDepth 30":

Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable
Compositing: Software only. Hardware acceleration disabled
Multiple Raster Threads: Enabled
Out-of-process Rasterization: Disabled
OpenGL: Disabled
Rasterization: Software only. Hardware acceleration disabled
Skia Renderer: Enabled
Video Decode: Software only. Hardware acceleration disabled
Vulkan: Disabled
WebGL: Software only, hardware acceleration unavailable
WebGL2: Software only, hardware acceleration unavailable

Your Chrome looks somewhat borked. This is mine:

I can see the vertical bars for grey and green in Linux, but not the blue and red.

Does that mean anything?

You should see 256 bars for the 10bit parts of the image, and only 64 bars for the 8bit parts.

Chrome, Firefox and native image Linux viewers all show me 64 bars.

Also, I've just verified that Firefox 92.0 doesn't support 30bit color either.

This image (30bit) looks the same in every tested mode, browser or application in Xorg/X11.

Under Windows you can see it as intended.

Neither mpv, nor ffplay can display 30bit videos either.

"Actually almost all studios use Linux for the desktop."
–"they tend to use Linux for servers"

And after you've been proven wrong, you now don't get the point. Oh man, you're hilarious. 🍿

"Cannot actually read properly" (or refuses to do so)
- "changes the definition of studio/workstation/desktop to suite the argument"

And after its been proven that you twist what people say and cannot comprehend finer details. Oh man your hilarious 🍿

Im literally watching a hdr video on youtube right now with chromium + nvidia + x11 and it works and chromium even detects and says that hdr is enabled on my system

Absolute most smartphone (cameras) output to JPEG which doesn't support HDR in any shape or form unfortunately, and people don't shoot videos in HDR because of humongous file sizes. HDR is still gimmicky as hell for most users out there even on Windows, of course rare HDR enabled games and rare movies notwithstanding.

Even prosumer cameras and professional DSLRs shoot to JPEG as the default capture mode unless specifically instructed otherwise.

[Awesomeness]

I don't get what your point here is.

And you know that Chrome/Chromium doesn't just bypass X11 for that like every software wanting to do something like that?
That HDR doesn't work with Wayland isn't because the capability hasn't been added yet, but mainly because Wayland is built to prevent all the hacky solutions from working that are used to get many things to work under X because X never supported those features itself.
