It is, but most systems aren't using a color managed workflow. And sRGB content on an sRGB screen looks exactly the same as on a DCI-P3 panel if you're using a color-managed workflow.
The only issue is that less than 15% of monitors today actually match the 95% sRGB, 300 nits, 8-bit panel specs which e.g. DisplayHDR 400 sets.
Just think about it, 85% of monitors can't actually display all CSS colors, and that doesn't even begin to handle issues like AdobeRGB, DCI-P3, and other WCG content.
On a true sRGB/300nits/8-bit screen #414141 on #dddddd contrast is actually fine (and meets WCAG guidelines, btw).
But if you display this same contrast on a 6-bit 150nits ~70% sRGB panel (standard cheap monitor from 2014) you won’t be able to read it under most conditions.
