> HDMI or DP display connections that have constrained data channels

HDMI has theoretical support for 100 MBit/s Ethernet [1] but in practice I agree, haven't seen that one used in practice.

IIRC it came in 2009 with HDMI 1.4, at that time Wifi in practice was mostly 802.11g with IIRC 20-ish MBit/s as 802.11n was still formally a draft... the idea was to give high-bandwidth networking to home entertainment devices without requiring to run physical Ethernet to each tiny device, but it quickly became superseded by 802.11n Wifi on one side, and on the other side, the "enrichment" of stuff on DVDs or broadcast TV with internet-based content never truly materialized.
