It might be worth noting that the OEM tunes this car richer than you suggest, would you consider that unhealthy?

I haven't seen anything richer than 0.85 lambda, and suspect this to be a dubious claim, as DI engines run quite a bit leaner under load than port injection engines.
Hotter in this context isn't hotter enough to be bad for valves or exhaust components. We're still talking being in MBT AFRs here.
