Xref of a function in the dyld shared cache

[matbrik]

Hi, I'm curious about the best way to approach this task with ipsw:
I'd like to find all the references to this function dyld_program_sdk_at_least in the dyld shared cache of ios 16.4(20E246__iPhone10,3_6)

with ipsw I tried 20E246__iPhone10,3_6 % ipsw dyld symaddr dyld_shared_cache_arm64 -a _dyld_program_sdk_at_least to find the address of the function and I got only a match in libdyld with an address but nothing in the others:

I tried to xref the address found to check where it is referenced with 20E246__iPhone10,3_6 % ipsw dyld xref dyld_shared_cache_arm64 0x1a6b707e4 but it didn't find anything

Looking at one of the frameworks listed above I found a reference to the function:

I'm missing something? Do you have suggestions on how to scan the whole dyld shared cache to easily find where a particular function is used?
