That's exactly my problem I'm having with my Xperia 1 IV, And just found a sort of FIX and here what to do:Same problem here.
Every update so far did not fix it.
Some specs and what I have tried:
- Android 12, Update 64.0.A.5.71
- Software repair and factory reset did not help.
- XQ-CT54 (EU, Germany)
- White balance does not fix it
- Creator/Vivid mode does not fix it
- 120/60 Hz does not fix it
- Brightness > 90% is good, and < 90% is bad on SDR
- Brightness < 50% is REALLY bad on HDR
The problem:
What I have noticed is that black gets "crushed". Banding or distortion, call it whatever you want. Near black greys turn either black or greenish grey. Looks like a green tint, especially noticable in HDR. Otherwise it is some very slight greenish tint. The green tint gets reduced minimally when using 60 Hz instead of 120 Hz. Conditions are the brightness is below 90% in SDR and below ~50% in HDR.
- When booting the device there is green artifacts around the logo.
See my pictures and the youtube video here showing the "pop" around 90% brightness:
Also check the artifacts in the MrMobile video around 6 seconds (or screenshot below):
This is exactly what the artifacts look like.

I have sent all evidence to Sony support and they told me yesterday to send it in to checkup and repair.
Tomorrow I will check if my friends Xperia 1 IV has the same issue.
But I am thinking this can be fixed with a software update, I mean ... It looks perfect on certain brightness levels.
UPDATE:
So I checked with my friends Xperia 1 IV and he has the same black clipping problem as I have. BUT he has no green tint. Same settings on both devices and his was looking so much more natural.
Also I found out, that my 120Hz mode makes it even greener.
So I am thinking the black clipping is a software calbration bug of the display, because it does not occur on brightness above 90%. Also the display itself seems calibrated wrong (software fix possible?) or it is bad batch by factory with the green tint.
I will contact Sony again and their repair service and see what can be done about this. This is so frustrating.
1- Turn off Auto Brightness
2- Set screen Brightness to 100%
3- Turn on Screen Dim to avoid the screen being too bright for eyes
And please note that screen problem is still there but less noticeable
