Denon AVR-X2300W 7.2 for £100 - is it worth for that price? Can it output HDR?

[mossi]

I got an offer for a Denon AVR-X2300W 7.2 for £100, is it worth buying for this price? Will it output HDR?

I want to have HDR in my HTPC. My current AVR Yamaha RX-V377 cannot output HDR via HDMI passthrough.

I have only really checked via Google. That suggests it didn't support HDR when released 8 years ago (was HDR a big thing back then?), but does now support it via a firmware update (at least HDR10 if not HDR10+).

I cannot easily find anything via the Denon site. Might be worth contacting them directly to clarify.
