I'm suggesting something that WON'T hurt your eyes. I don't see how that's so hard to understand.

You set a comfortable max brightness for the entire screen.

Comfortable max brightness for small parts of the screen is a different brightness. Comfortable. NO eye hurting.

It's still uncomfortable to have 10% of the screen get ridiculously bright.

Yes, it's uncomfortable to have it get "ridiculously" bright.

But there's a level that is comfortable that is higher than what you set for FFFFFF.

And the comfortable level for 1% of the screen is even higher.

HDR could take advantage of that to make more realistic scenes without making you uncomfortable. If it was coded right to respect your limits. Which is probably isn't right now. But it could be.

I severely doubt that I could ever be comfortable with 10% of my screen getting much brighter than the value I set as max brightness.

But say you're right. Now you've achieved images looking completely out of place. You've achieved making the surrounding GUI look grey instead of white. And the screen looks broken when it suddenly dims after switching tabs away from one with an HDR video. What's the point? Even ignoring the painful aspects (which is a big thing to ignore, since my laptop currently physically hurts me at night with no setting to make it not hurt me, which I don't appreciate), you're just making the experience of browsing the web worse. Why?

In general, people report that HDR content looks more realistic and pretty. That's the point, if it can be done without hurting you.

Do they? Do people report that an HDR image on a web page that takes up roughly 10% of the screen looks more realistic? Do they report that an HDR YouTube video, which mostly consists of a screen recording with the recorded SDR FFF being mapped to the brightness of the sun, looks pretty? Do people like when their light-mode GUI suddenly turns grey as a part of it becomes 10x the brightness of what used to be white? (see e.g https://floss.social/@mort/115147174361502259)

Because that's what HDR web content is.

HDR movies playing on a livingroom TV? Sure, nothing against that. I mean it's stupid that it tries to achieve some kind of absolute brightness, but in principle, some form of "brighter than SDR FFF" could make sense there. But for web content, surrounded by an SDR GUI?

I don't know why you're asking me about examples that violate the rules I proposed. No I don't want that.

And obviously boosting the brightness of a screen capture is bad. It would look bad in SDR too. I don't know why you're even bringing it up. I am aware that HDR can be done wrong...

But for HDR videos where the HDR actually makes sense, yeah it's fine for highlights in the video to be a little brighter than the GUI around them, or for tiny little blips to be significantly brighter. Not enough to make it look gray like the misbehavior you linked.
