No, its only slower over PTY because the kitty protocol is transmitting images with higher fidelity, aka color accuracy. So if you want to compare apples to apples get sixel to transmit images with equal fidelity first. I'll go raise three generations of my family while you try to achieve that.

As for infinitely faster, that was obvious hyperbole. For local transmission, using shared memory to transmit RGBA data directly is going to absolutely crush serializing then transmitting over a pipe the de serializing. This is so obvious it doesnt even need to be stated. And the vast majority of image display and indeed terminal usage in general happens locally not remotely. Which is why the kityt protocol sensibly prioritizes that use case.
