Most binary distributions don’t have different sets of packages for different feature sets of 64-bit Intel processors. Most containers use the same exact binaries the given distribution would on bare metal.
The processor won’t (and AFAIK can’t) report different feature sets for processes running in a Docker container, and most heavy optimized numerical libraries will choose to use things like AVX at runtime, not compile time.
