What exactly makes something compressible??

Just a general question here, i already know that motion requires more bitrate, noise/grain requires more bitrate, lots of complex motion like confetti or snow can have a similar effect to noise, but what else? I have the bluray for pennyworth season 1 and it seems to be the most easily compressed content i have. Using veryslow crf 18 film tune with x264, i was often getting just a couple of mbits, even tho the average for that preset was more like 10 to 12. X265 veryslow crf 20 was often less than 1 mbit, maybe 600-800 kbits. This is all 1080p24. Nothing in particularl stands out to me why this would be so easily compressed. Its not noisy, but its no cleaner than some other content. Theres a fair amount of action, i have lots of stuff with less. So what makes this so easy?
