I think you large ring is fine. The teeth profile are different on "modern" chainrings, they are not uniform by design. The teeth just "after" the shift pins are lower to assist with the chain engaging with the large ring. I have seen this explained better elsewhere on the internet (believe there is even a video showing this). I only change the chainring if I start getting chain suck or, after installing a new chain, I get audible grinding/clicking or other unpleasant sounds indicating the new chain isn't meshing well on the old ring.
