And the HDMI is pretty much a direct digital translation of analogue CRT signalling, blanking and timing weirdness included. Which is also not how modern LCDs implement their internal screen driving, so needs a similar level of complexity to decode and convert. I think the biggest difference in DP vs HDMI cost is simply scale - there's probably orders of magnitude more HDMI chips sold than DP.
