I think you will find the days of the 1.4 million dot EVF are confined to older cheap cameras such as the Sony A6000 ..... the Nikon Z6/Z7 have 3.6 million dots ..... the Z50 2.6 million dots.
 I tried the Z6 and the EVF was shall we say ....... not to my taste!

Silly me, before posting I checked the specs of the A9II, then double checked them as indeed the value was lower than it should've been, but all this time I was looking at the LCD's resolution!
But even 3.6m dots doesn't change anything. Though I admit, the highest resolution EVF I've seen was 2.4-ish.

I tried the Z6/7 and the EOS R at Photokina... well, the EVFs are getting better and better but there's a trick: for those who already like them.
If it doesn't work for you, bad luck, there's little to no addressing such issues. And honestly I don't know what they could do, since the concept is unchanged - a miniature TV centimeters in front of your eyes.

 The Panasonic SH1 has an EVF of 5.76 million dots !
