few questions about this fantastic tool

1. I see there's no M4 support. is this a hardware issue, or do you think that with enough time support could be brought to m4 as well? or is it forever impossible . I personally use M1 but curious 2. when will I notice it, I mean when is the loss of 2 bits apparent ? 3.will it affect the screen of a macbook pro mini led ? will it still be able to play hdr content ? 4.what about a LG oled hdr monitor ? will the monitor play 10bits hdr just fine ?
