I haven't ran across websites that serves up HDR images, I am not sure I would notice the difference. WebP seems appropriately named and optimized for image delivery on the web.
Maybe you are thinking of high bit depth for archival use? I can see some use cases there where 8-bit is not sufficient, though personally I store high bit depth images in whatever raw format was produced by my camera (which is usually some variant of TIFF).
8-bit can have banding even without "HDR". Definitely not enough. 10 bit HDR video is becoming more common, and popularity for images will follow. Adoption is hampered by the fact that Windows has bad HDR support, but it all works plenty well on macOS and mobile platforms.
unfortunately linux HDR is pretty much completely absent. That said, Wayland slowly looks like it's getting there.
KDE Plasma 6 has HDR support.

X11 supports 10-bit SDR… which Wayland doesn’t
