The GPU and monitor combination has full 10-bit HDR in Windows. But in Linux it's stuck at 8bpp due to nVidia driver not having 10-bit RGB output.
That's still pretty crappy. Monitors do not say whether they support BGR input signals or not as opposed to RGB.
I'm actually surprised that YouTube HDR works on your side - perhaps it's tied to the ABGR2101010 output mode being available.
Here's what I'm getting on both monitors, with HDR enabled on Gnome 49: https://imgur.com/a/SCyyZWt
Maybe you're lucky with the Dell. But as I understand, HDR playback on Chrome is still broken.
Here's what I'm getting on an RTX 4090 / InnoCN 27M2V and Cooler Master Tempest GP27U.
Also, go to YouTube and play this video: https://www.youtube.com/watch?v=onVhbeY7nLM
Do it once on "HDR" on Linux, and then on Windows. The "HDR" in nVidia/Linux is fake.
The brightness you see on Plasma or Mutter is indeed related to the HDR support in the driver. But - it's not really useful for the most common HDR tasks at the moment.
1. 10bpp color depth is not supported on RGB monitors, which are the majority of LCD displays on the market. Concretely, ARGB2101010 and XRGB2101010 modes are not supported by current nVidia Linux drivers - the drivers only offer ABGR2101010 and XBGR2101010 (See: https://github.com/NVIDIA/open-gpu-kernel-modules/blob/main/...).
2. Common browsers like Chrome and Firefox has no real support for HDR video playback on nVidia Linux drivers. The "HDR" option appears on YouTube, but no HDR color can be displayed with an nVidia GPU.
Also, video backgrounds in Google Meet on Chrome are broken with nVidia GPUs and Wayland. Ironically it works on Firefox. This has been broken for a few years and no fix is in sight.
The "HDR" toggle you get on Plasma or Mutter is hiding a ton of problems behind the scenes. If you only have 8bpp, even if you can find an app that somehow displays HDR colors on nVidia/Wayland - you'll see artifacts on color gradients.
If you're a mosquito OTOH... even enslavement is not worth it. It's eradication.
Let's say you're the person who's speaking for Wells Fargo at that moment - you absolutely don't want to give the public any reason to test whether 28% is safe or not. 3 months later, when people are no longer panicking, and cooler heads want to start discussing what're the safety measures to put onto banks - maybe. But seriously not right now. Let's say you quote the 28% number to say your bank is maybe safer than SVB - but the moment the reporter asks whether 28% is safe enough or not, or how about another bank that have more or less, you'd probably realize you shouldn't have said too much already.
So, at this moment... if you're a spokesperson for a bank or a bank regulator - "We're safe. SVB is a special case" is pretty much the only appropriate response right now.
You generally only get good at interview problems when you're entering the door. After that, interview questions generally have nothing to do with your job.
Also, as you move beyond entry level positions, political skills, communications skills and connections becomes more and more important. Unless you happen to be at some massive growth teams at the right times, it's basically impossible to move beyond ICT4 or L5 unless both you and your boss have very good grasp of politics.
My monitors (InnoCN 27M2V and Cooler Master GP27U) require RGB input, which means it's limited to 8bpp even with HDR enabled on Wayland. There's another commentator below who uses a Dell monitor and manages to get BGR input working and full HDR in nVidia/Linux.
