Betreff: Overexposed desktop

hello, for whatever reason, the next time I've booted up, my desktop became 
completley black. I mean, the graphical login was visible, the black screen was 
happening after logging in.
I tried different desktops, that were installed: Gnome 3, Unity, LXDE, Xfce, 
but i was always getting black screen. I don't know, why it happened. Possibly, 
something got updated and it caused this problem.
It happened about a 2 months ago. After spending a couple of days 
troubleshooting it, nothing helped, so I desided to do the unthinkable, upgrade 
my LTS 22.04 Ubuntu to the latest version, that was at the time 23.04. It fixed 
the black screen, but the picture became overexposed:

I tried to install drivers from different unofficial repositories, but none of 
them changed the situation, so I returned the drivers from the official 
repository.
I tried using xrandr and other utilities to change contrast, brightness and 
gamma with using reference pictures for adjusting those values, but it didn't 
help. White range was still cut off after certain value, but it just became 
more dimm, when I tried to lower those values and lower range of blacks was cut 
off on the lower range even when trying to raise those values.
The only time, when picture became normal was, when I loaded LXDE and openbox:

Gnome 3, Unity and Xfce were openexposed.
I tried to do: openbox --replace after loading different DE, but it didn't work 
with Gnome 3 and Unity, but it worked on Xfce. Also, metacity --replace works 
on Xfce, but, even though, it mostly looks normal on Xfce, some programs still 
are overexposed.
I think, the programs, that have modern interfaces. Some pdf/fb2/epub readers, 
Blender, mpv, GoDot, etc, Ubuntu's Software store are still overexposed even in 
xfce or lxde with openbox or metacity.

I've noticed one thing, when loading the Desktop Environment:
On login screen the picture is normal, not overexposed.
Then, after entering username/password, the desktop starts loading normal (not 
overexposed).
Then, a few seconds after login screen disappears, while still seeing a wall 
paper, over desktops, seems like some transparent rectangle gets loaded taking 
almost an entire screen, not reaching edges only about 1 centimeter around it 
and under it's transparency, the wallpaper gets overexposed, then shortly after 
the whole screen gets overexposed.

I tried to disable all the programs, that autostart, but none of them cause it.
Maybe there is something gets loaded by system, that causes it.
