What's the difference between the H815 and the H815L

Hello, I'm the owner of the H815L (official Israely version) variant for about a month. The only differences that I have noticed between the H815 and the H815L are the bootloader and some minor change in the LTE network (for the IL network). But basically I infer that they are the same in hardware and software (expt the things bellow). So my question is to know the differences between those two variants because I would like to install TWRP on it and also CM 12.1 and maybe some custom kernel. So I thought that if there's not much difference between those two models maybe I could install on my device those versions for the H815 (because there won't be much support for this model).

Can you help me with this and tell me the differences and if could do the actions that available for the international version?
Thanks

What is the difference between FOG6 and FOF6?

I'm sorry, I searched the forum but can't seem to find the answer; What are the differences between the FOG and FOF versions? I have an S5 custom rom with the 0B1 baseband that I'd like to bring back to stock, but I'm not sure what to use or what to avoid. Thank you.
