SCC tools are completely useless except for screen content. It is very strong in video conferencing though. What you did is like saying PNG performs higher than JPEG.
CABAC is the entropy coder by the way, not a tool like SCC, you compared an Apple with an Orange.
Are you just typing words in google and use some GPT3 model to generate these forum posts ?

I am pretty sure I am not GPT3, thank you very much, though I did test that 4chan model, model that was banned everywhere, nice one. SCC is a profile, just like HIGH 10 and predictive, which you would know if you looked into not yet merged decoding patches for ffmpeg. PNG does indeed perfom much better, smaller size, for screenshots on my phone, because vector graphics and when there is no crazy color subpixel rendering, like in google drive pdf app, e.g. and anyway, the support is not yet added into overoptimised x265, so there is no way to say whether it will be better for camera images, I saw that YUV is indeed 0% better for lossless and even slightly worse for lossy. What I think you completly missed is it is much better for RGB camera captured, lossy not lossless. That is one of key moments why AV1 is better for RGB.
