On my phone, all i see is empty white image. Is that supposed to be a joke or is my device/browser not supporting HDR?

If it just looks like an ordinary white square then it's not displaying with HDR. Could be unsupported or maybe disabled.

You're lucky. On a real HDR display it shows a rectangle with the brightness of the Sun!
