The peak brightness of HDR displays is routinely measured on a 10% window.
Ask yourself how Apple measured it. Or even better, talk to the people who did it. ;)
In no universe would anyone want to watch an HDR show where the entire screen was 1,600 nits.
Think about what you wrote there... "entire screen" and "nits", then figure out what doesn't make sense. You only have to understand what the definition of a nit is. It's simple physics in the end.

Your reply makes no sense whatsoever so I can’t really respond but I’ll do better still. I suggest you educate yourself rather than leave illogical remarks on a public forum for all to see.

Of course you can't respond, because you don't understand it. I don't have to educate myself sorry, nice try. In fact, I'm teaching this stuff next to research at a university. Why don't you get a PhD first in a relevant field and then come back? I've been part of the team that came up with h264 back when MS was working on VC-1 at the same time. I've done consulting for the company that manufactures material for LG and Samsung to build these screens and I regularly measure displays with NIST certified equipment. On the other hand, you don't understand the physical definition of a nit. Go figure, have fun ranting kid. ?
 
Not so, not only can one watch HDR content on Vimeo and YouTube, there is also tons of HDR content available on streaming networks Apple TV+ and Netflix. Running on a Mac with macOS!
Apple TV/iTunes, Netflix, and YouTube are the only ones with 4K HDR support on mac right now. Tons of stuff that offers 4K HDR on iOS and Apple TV are limited to 1080p SDR in a browser, like hbo, Hulu, and Disney. Amazon prime just released a native Mac app, I hope the others follow suit.

All that said, I would still like to see SDR content be able to take advantage of the 1000 sustained nits the display can obviously provide. It’s a silly limitation!

So what - HDR is a real mess on Windows laptops as well, and support for the content you mentioned is sketchy or non-existent on other platforms, too! For viewing HDR content on a laptop, no other brand approaches the brightness level, color accuracy, battery life and refinement of the new Macs and many have super nasty reflective screens that wash out blacks, destroying the picture.

Not true. iOS and Apple TV support 4K and HDR on every single major streaming platform. macOS does not. I don’t run windows so I don’t care how it performs, I’m not surprised to hear the situation is even worse. I would love for my Mac to replace my iPad for mobile viewing, but because of its browser based limitations I cannot :(
