Got around to taking some pics at dawn. Brightness seems to not be impacted too much (I'll take pics next to an untinted i4 when we get around to doing the meetup in the summer). There's also the third brake light for braking!
I asked BMW about the M Performance diffuser, and was told that it was >$3k CAD before installation! I don't even like the CF, which is the most expensive part. I just like the shape; if it was available in gloss black for cheaper, I'd consider it. Hoping more options become available on AliExpress soon! There is currently one, but it's CF, and doesn't look as nice as the M Perf version.
