@Chikins thanks - yes we do try to fit to each monitor's "chromaticities" (the colors they use for R, G, and B) - assuming your new ASUS is a wider gamut display than the rest? For matching exactly you may need a color profile for each one.
This review has a profile you could try for the ASUS: https://www.rtings.com/monitor/reviews/asus/tuf-gaming-vg27aql1a
