Firmwares for SOHO routers are using LZMA to pack firmwares, there is tool called binwalk, its written in python and if you using python 2 and have python-lzma installed binwalik will validate found headers an false-positives will be excluded from search, something simmilar could be done for quickbms I think, its idea

Good. Anyway I have added zstd to the list in the first post since it uses a magic number that allow to guess it at 100%.

Was looking for zstd compression recognising technique and was about to ask in a thread. But here I found 100% success technique. Thanks for mentioning the magic number, this solves my problem I was facing in my current project.
