You are trying to do colour management on the web, and also likely in the general consumer PC space. This is impossible, and will remain so for at least a decade. No vendor other than Apple has the slightest interest in getting colour even vaguely right, because they're all run either by colorblind lizards, or have corporate drones that are given identical monitors. The cheapest monitors possible that are basically greyscale. Recently, Windows has taken several steps back from Vista's fairly good colour management. For example, the newer Win UI 3 SDK is 8-bit sRGB SDR only. Similarly, HDR support on Windows 11 is totally broken, and every semi-annual release does random things to it. When bugs are identified by consumers (not Microsoft!), they delay the fixes to the next semiannual release... at which they break other things. There hasn't been a release of Windows ever that can correctly drive a directly attached HDR display, such as the type used in a laptop. None of these corporate drones understand the problem because they literally cannot see it.
