DVI and HDMI are actually the same video signal. Which is why adapters are so cheap.
DP can carry an HDMI encoded signal (and thus a DVI signal), which is why DP->HDMI and DP->DVI adapters are so cheap. It's called DP Dual Mode or Multi Mode or something like that.
I haven't encountered a device that outputs DisplayPort that cannot output the Dual Mode HDMI encoded signal as well.

HDMI/DVI->DP is an active conversion - ie it is re-encoding it. Which is why the converters are significantly more expensive.

However, it's all digital. If the signal quality degrades, it will be very obvious because it stops working (sparkles on a black screen, lines, flashes, all sorts).
