Upgrade display?

Hello friends

I am not sure if it is appropriate to post this type of question on this forum. I chose it because I use my set up for Photoshop. If I have erred, please accept my apologies and redirect me if possible.

I am in the process of upgrading my computer to a new 2018 Mac Mini and am wondering whether there is any need to consider upgrading my monitor. I presently use a NEC MultiSync PA241W-BK-SV 24.1" Widescreen LCD Monitor with included SpectraViewII Color Calibration Solution (including an Xrite sensor) which I purchased in 2011. At the time I bought it it was specified to have a gamut equal to 98% of the Adobe 1998 RGB color space. As far as I can tell it still works fine. However, 7 years is a long time in "Moore's Law tech years", so I wonder what, if anything, the newest monitors have to offer that my present monitor does not? It appears from the descriptions that some have higher resolution and some have "internal calibration" that allows you to switch from Adobe 1998 RGB to SRGB by pushing a button. What else has improved in monitor technology, and do you see any reason for me to upgrade? I use the set up for photo editing.

Many thanks!
