The design language matches what we've seen across other CBS News properties. It definitely might not be the final form, but I can guarantee that it's something that was thrown out.
While the 2016 package, in its original state, is totally fine, so many stations have tweaked their own looks to the point where there are some major inconsistencies, from market to market. Post-Moonves CBS has created a unifying brand that, at least to me, is meant to keep everyone in-line. And for the record, TT Norms is not, and was never previously the font for the 2016 package. That lack of attention to detail pokes some holes in this opinion.
All signs point to KABC having a new look on the horizon (within the year, weeks, or even days), with the current package lasting so long only because the final details of a groupwide look are being ironed out. And your thought about KTLA is shared with me.
