I looked into basically all of this when I did Link's Awakening and decided that it was better for me if I added the border in post rather than trying to make the border part of the original footage.
BGB is a Super Game Boy as far as the game itself can see - it pulls the border directly from the game and tells it to use SGB palettes, and for the most part these two things are what people care about when they want SGB mode.
However, none of the other toys that come with being in SGB mode (changing the palettes using
only the controller, arting the screen, being able to 'edit' the border while the game is running, having the border be directly part of the video output) are built into BGB. This is because they're handled by the SNES (the SNES programming for these toys is in the SGB cart's firmware, which DMG emulators don't know what to do with as - to my understanding, anyway - it's written for a completely different system).
tl;dr: BGB isn't actually doing SGB because SGB is a SNES being a hypervisor for a physical DMG unit (albeit one without its own power source or video output or controller). However, for most purposes what BGB does do is enough.
