That doesn't make sense, especially when you consider how the digital system works, with things like I, P and B frames. https://en.wikipedia.org/wiki/Video_compression_picture_types
Compressed video is not related to how the signal is sent over HDMI. HDMI is sending uncompressed frames (not counting DSC as used sometimes for 8K video on HDMI).
As you mentioned blanking intervals are a relic of analog TV, dating back before WW2. There is absolutely no need for them with digital TV.
Supposedly HDMI is using some of the blanking space to send audio, so I guess it has some use. -- Len Sorensen
