So... any idea why it's so bad?

  The main reason is probably that 1080p30 is 1580 MBits and USB2 is only 480 MBits, so it has to do decompression.

    Can you explain why you mention USB? It's Lightning to HDMI...

  It’s just bad. As a product, it’s bad. Terrible quality, compression artifacts etc. From a design approach perspective it’s bad because, lightning has USB 2.0 bandwidth only. So they had to build an airplay server on the dongle that decodes a compressed H.264 and outputs an HDMI signal. There are better ways of doing that. One way is to actually have enough pins on the standard to support uncompressed HDMI output like USB-C
