Here’s how its done on Android. It might necessary to make apps able to choose which colour profile they use.

This is a comparison with another phone with oled screen, just to show what j2 shows and how black should have been.
Slightly more exaggerated result due to phone camera at night, but just to show how big of an issue it is.
And the display always has this green/yellow hue.

Why is this an answer to my post?
The post is to inform everyone ofc.
But I think this is a huge issue for any phone, not just for what the users want to see so I thought I would reply to your comment as well.

might get prioritized.

Is this real? Where exactly did the source come from? I really hope it isn’t real.
I can’t read that language and can’t select it to translate 
Do you maybe have a source where I can select it?
Or can someone kindly post a summary in english?
Thanks for bringing it to attention anyway

Jolla’s display color errors are striking. For example, the display on the €300 Honor 600 Lite is significantly better than Jolla’s.
Jolla also lacks the extra-brightness mode that activates in bright lighting, such as the one found on Apple’s iPhone 17e, and brightness below 600 nits means there will be readability issues in direct sunlight.
DISPLAY COLOR ERRORS
dE2000 — lower is better
-
Apple iPhone 17e: 2.08 / 3.32
-
Honor 600 Lite: 2.09 / 3.15
-
Samsung Galaxy A57: 2.38 / 3.98
-
Jolla Phone: 7.39 / 11.78
edit: @kenny2999 Please explain the source already. Where did you get it from? Where did you access this information?

The Finnish text translates to:
“Some display color errors are glaring. For example, the €300 Honor 600 Lite is significantly better than the Jolla. Unlike the Apple iPhone 17e, the Jolla does not have extra brightness that activates in bright lighting conditions, and brightness below 600 nits means readability problems in sunlight.”

ΔE2000, lower is better

Honor 600 Lite: 2.09 / 3.15
Samsung Galaxy A57: 2.38 / 3.98

The chart is measuring display color accuracy using ΔE2000 (a standard color difference metric). Lower numbers mean colors are closer to the intended values. The Jolla Phone performs much worse than the other phones in this comparison.

Thanks everyone for the translation and the tip to auto-translate pictures! My android-laden brain only knew about framing pictures with google lens but thanks to you I’m getting better every day.
I don’t know if the report is accurate, I never worked with images or color grading.
To my brain the color issues of the display are evident, but I don’t suffer them as much as this graph suggests (probably because I used to have night light permanently active on my old FP4). Still the difference is noticeable, especially at low brightness levels.
I hope it gets prioritised along with the mobile network issues since in my experience those are the most glaring ones to a new user (or at least they are for me, everything else just worked or was very easy to make work - I opened the terminal 2 times so far and just for pasting, my Jolla 2026 would be a daily driver if I didn’t have network issues)
The biggest issue with this report is that it claims the phone’s display itself is poor quality. That’s the most worrying part.

Reviewers won’t breakdown what software parts do not work etc, they will judge the result.
And the fact is that right now the display is one of the worst you would ever see because it just shows a green hue everywhere and brightness is low. This is not a budget device or age related thing, it’s just flawed on any price or quality segment.
That aside, we are well aware that a new notched display is probably the cheapest oled you can source. That was never a surprise.

Source was Mikrobitti a computer magazine in Finland. The display measures worse than it looks but that graph isn’t doing jolla any favors.

Found something interesting.
There is this test, where a photo is attached with a custom colour profile. If the words align with the colour, that app respects the colour profile and vice versa.
In the native browser its not respected, while in Vivaldi it is (see attached photo). That hints that the AAS has some colour management baked in, while native SFOS apps don’t have that feature accessible.

I get the same results.
But black is still not pure black in aas, browser or dedicated screen testing apps.
Interesting observation, but i don’t think this has anything to do with the screen calibration.
While the actual panel model is super difficult to find through software, it’s very likely a LCD panel making the blacks a hardware problem.
LCD? 
I hope it isn’t. I don’t think it’s that bad. I actually think Jolla needs to investigate this, because no matter how much we research it or dig into it, we still can’t make 100% sense of the situation.
According to the specs it is AmoLED
