> A similar problem comes up when trying to manage color gamut on screens and systems that are intentionally blown out to look vivid, vibrant, shiny… looking at you Samsung phones.
This is a problem on a lot of HDR-capable consumer monitors, even expensive factory calibrated ones from Dell. They often lack any form of sRGB clamp resulting in exactly this problem when viewing an sRGB signal. AMD has a setting in their GPU driver control panel that can do this on the GPU without needing the user to provide an ICC profile. The Nvidia driver has a hidden API to do this, requiring the use of third party software to take advantage of.[1]
TVs are a little better in this regard. My Samsung TV has an "Auto" option for color gamut that correctly identifies DCI-P3 and sRGB signals and clamps them accordingly. But the default setting was "native" which made sRGB content look really bad.
