TBH I don't know how Mac to Mac Screen Sharing works, but that's an educated guess.

When you connect on another Mac, your server Mac probably knows its connecting to a Mac client so probably uses AirPlay, which uses an HEVC encoder as mentioned.

You could try TightVNC which adds a layer of zlib compression to speed things up, but I don't know if the Mac OS VNC server supports that extension to the VNC protocol. If you did the same and connected your Mac to a VNC server on your Linux box, you'd see the same performance issue. Just think of it like a tool that hits the PrtScr button a bunch of times for you automatically, and sends the results over the wire. It's basically a slideshow of JPEGs of what your desktop looks like. VNC is not really sending a video stream, it's sending a bunch of JPEG screengrabs. It's the fact your Mac is encoding your entire desktop into garbage quality JPEG which for one is lossy and for two is a pretty crappy compression algorithm compared to something more modern. VNC is not hardware accelerated for either decoding or encoding. Why can't it decode this video faster than a 2015 MPB with an Intel Iris? If you ripped the video card out of an old PowerMac/Mac Pro, it would feel like your VNC session. MacOS uses graphics acceleration and then encodes a video.
