That's a weird read having in mind I had to move to Wayland because x11 had severe screen tearing. I would have guessed Wayland had better support.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Wayland has a bunch of features that are so new they aren't in the stable distros yet.
Nvidia went from declaring they were never going to support Wayland to trying to force their own EGLStreams stuff on everybody to reluctantly accepting the standard that was developed without them and trying to make it work for their driver. They're playing catchup and it's entirely their own fault for refusing to cooperate with anybody.
They're moving more towards open source drivers now, probably because the people buying billions of dollars worth of GPUs to use on Linux servers for AI training have had words with Nvidia on the subject.
reluctantly accepting the standard that was developed without them
Not with everything, Nvidia stood still on explicit sync, in that case it were the idiots at Freedesktop that were massively blocking Wayland's progress, trying to force an inferior technology, which Nvidia did not want to implement.
Okay, but that's still partially on Nvidia for refusing to participate. They could have argued for explicit sync early in Wayland's development but they weren't at the table at all, so they got stuck with the technology that was decided on without them and had to argue for changes much later.
And they started off arguing for EGLStreams, but it didn't work well either. Explicit sync came later.
EGLStreams is not superior to GBM.
It is better, just not on NVIDIA GPUs.
if your work requires CUDA then nvidia is the only option
Where does CUDA come into play for screen tearing?
How does AMD compare ?
They're in the It Just works category.
Yeah, but what works? I just plugged my AMD GPU in my PC running Bazzite and it was my best experience ever with a PC. But I want to know what is AMD working on, specially if it has to do with the RT / HDR / color management areas.

HDR/Color Management is not really AMD’s job. That’s between the Wayland and Mesa guys (I guess you could say AMD belongs in the “Mesa guys” umbrella).
Also, I’m pretty sure AMD already supports ray tracing through Mesa, and is enabled by default since version 23.2 on the radv driver:
