I switched on DLAA today to check it out, and something caught my eye as being different about nameplates.
I focused in on it, and noticed it got "fuzzy" - to use a technical term. There appears to be some horizontal fuzziness (best way I can describe it) or flickering. I turned off reshade, and that didn't help.
I uploaded to youtube, and you can still sort of see what's happening if you view full 1440p:

For comparison, here's FXAA that does not have the nameplate fuzziness:
