Yes, what the code “does” (the “result” of the code) does not differ.
However, “practical implications” are there for the empowered user, who uses the code (and/or other parts of the system, translation files etc) itself, whereas other users might just use the result of the code, which calculates the same independent of its license.
Isn’t there the aspect that the quality of code usually is better with open source due to “many eyes” inspecting it? I see posts in different contexts online every now and then about open source code being beautifully written, minimalistic and trimmed in contrast to proprietary code projects in different places being accused of being buggy, big and bloated.
But a line of code is the same line of code and has the same practicality of course regardless of license, except, as you wrote, that there are other practical benefits of the open source code. Hope I’m adding anything of value.
