Show HN: Make your logo extra bright on HDR screens
Certain logos started standing out to me on LinkedIn as brighter/whiter than everything else around them.I dug in and found out this is accomplished by adding a gain-map to an existing JPEG, visible only on HDR screens like a newer MacBook Pro. LinkedIn is the only social network I've found that isn't stripping them out, but of course you serve them up on your own site.I worked with Claude Code to turn it into a little browser-based utility (no registration) and hope you find it useful!

You know it will be annoying.
But I agree that app developers shouldn’t do this, or should at least provide an option to turn it off. (Some apps allow customizing the app icon color, so it seems that should be possible.)
chrome://flags/#force-color-profile -> sRGB
What are you talking about? I have a HDR display, in Chrome on Arch the literal only change in the submission's demo is the brightness of that particular element, doesn't change anything else on the screen, sounds like you have a broken HDR implementation.
Still, even with the best intent what you suggest is still annoying. Okay, you got my attention, i now know what you wanted me to know. Are you going to nag me for all eternity?
This way we get to skip awareness, interest and desire and get the prospect straight to action.
> Clearly we need more of it
I do not in fact want sites trying to get around my display preferences to post their visual presence on screen.
The Metapho app on iOS seems to be a good app to view the gain map itself. I give it no access to my photos and use the share sheet to view gain maps of specific images.

Android's HDR brightness slider is low - The single most common "HDR does nothing" report on Android 15/16 devices. Samsung also has Super HDR/Extra brightness / Vision booster toggles under Display. Any of them at the conservative setting would have an effect.
If I went down to say 50% brightness then it was much more pronounced, but who lives their life with their eyes only half open like that?!
