Any crypto that prevents casual tinkering is enough to keep most companies from wasting resources on reverse engineering stuff.
Back in the day we wrote a simple byte-level nonce + delta obfuscator for a terrible Node-RED-like programming environment so that we could tick a "must not be human-readable" requirements checkbox.
If the cryptography, proper or not, has been written for DRM purposes, no legal department is going to permit digging into implementation details even with a ten feet pole.
