E-M1 II has the worst EVF I've ever used, extremely washed out colours and low refresh rate. Otherwise it is a pretty good camera.
I bought one in October 2021 and here is my user review:

I mostly write about stuff I discover that is not mentioned in other reviews. I recommend reading my further posts in the thread where I provide more info as I discovered more things. I wrote extensively about the EVF problem and spent time figuring out what is likely wrong. Seems to be a firmware problem that Olympus never bothered fixing.

Here is a nice OM-1 review by someone who owns the E-M1 II, E-M1 III, and E-M1X. He really likes the OM-1 EVF:

He writes this:
As for the new EVF - I’m in love. After looking through the EVF on the OM-1, it’s hard to imagine ever going back to the washed-out 2.3 MP panel on the E-M1 X or III. The previous EVF was not horrible by 2014 standards, but having seen multiple generations of flagship camera, it was clearly time for an upgrade. I can’t overemphasize how drastic an improvement it is being able to accurately judge focus, exposure, and to review photographs with the new screen. To me, this was one of the biggest reasons to upgrade. OM needed to ace the EVF with their new camera - and they did. Finally, an Olympus camera with a great EVF. That’s enough WOW for me!
I don't know what he means when he says "washed out", but I suspect a lot of it has to do with my much more careful, descriptive dislike after lots of investigation that I wrote about in this thread. Stuff such as this:
There is a problem with the E-M1 II EVF firmware that doesn't exist in any of my other Olympus bodies. The problem with the E-M1 II is not the EVF hardware (which is quite good), it is a bug/deficiency in the firmware that doesn't exist in the PEN-F (OLED), E-M10 II (OLED), E-M10 (TFT LCD), etc. Since the last firmware is 3.5 and the E-M1 II is no longer a current flagship model it is very unlikely that OMDS will fix this bug. Specifically the Auto Luminance setting is broken in this model. I dug into the problem and wrote about it in detail in the following 3 posts. You need to read them to understand what is wrong with the E-M1 II firmware and what the ramifications are:

For the last 5 years I have seen many posts from people expressing disappointment in the E-M1 II EVF, but no one investigated and went into detail like I did about what was wrong and narrowed it down like I did. Certainly the EVF is still very usable and the camera has many other great things going for it, but that just makes this Olympus blunder even more annoying.
If you read my 3 posts that I linked to in my review above you will see that for 2 months I have gone back and forth with Auto Luminance on and off. Neither one is really ideal and works well in all general photo taking conditions. When one is better the other may not be and vice versa. It seems to depend on lighting, subject, mix of light and dark, etc. that probably causes the Auto Luminance algorithm to make EVF adjustments. My PEN-F, E-M10 II, E-M10, and E-M5 do not have this unfortunate behavior. Over the years there have been many vague comments by users on this forum and other forums and also sometimes in reviews about how the E-M1 II EVF is not quite as good as some other Olympus bodies (not talking about size or resolution) (using probably all versions of the firmware). Usually things are said such as sort of washed out, low contrast, etc. No more detail or better description. No one bothered to look into it until I did. And I gave a much better description. Auto Luminance is dynamic so it is difficult to give a pat description because it changes its behavior depending on what the camera sees. I bet most people didn't even know there is an Auto Luminance and it is turned ON by default. Most never tried turning it off and experimenting. Probably no one had until me.
As you will see in the 3 posts I linked to, I said this was not a major problem and the camera is still very usable. And great in pretty much every other way. I hold the flagship to a higher standard though. It was US$2000 when it came out so much more expensive than the other models. The EVF should be at least as good as my E-M10, E-M10 II, and PEN-F. I am convinced this is a firmware problem with Auto Luminance. It just doesn't behave well all the time. Sometimes it does. It is a dynamic thing. It is as if they didn't tune it properly for the EVF panel, but did for the lower level cameras.
