What are losted after unlocking bootloader? - Sony Xperia XZ2 Questions & Answers

Hello all,
I know unlocking the bootloader will lost some functionalities but what are losted is a bit vague. Some say the camera will green screen and some say it won't. I'm very confused.
I specifically want to know if unlocking the bootloader will affect screen quality, e.g. color accuracy, white balance, HDR.
I also found out the TA partion can be backed up but had anyone able to restore it after?
Thanks in advance.

Understanding what one loses when switching from stock to AOSP

Hi there. A friend I'm helping out with has a Z3 Compact. She doesn't like a bunch of the bloat that comes with the stock experience. I was thinking of helping her install AOSP on the device, but have heard around the water cooler that you do lose more than just the stock bloat ware. So far it sounds like the main big points that are lost are...
- Better camera for night time shots
- Better over all power management/saving
Is there anything I'm missing?
Beyond that, I'm wondering if there's a prebuilt AOSP based rom that has the camera and possibly the power management stuff rolled into it?
Thanks!
Basically if you want to switch to AOSP, you have to unlock the bootloader. When unlocking, it's recommended to backup .ta partition (so you can restore it when locking the bootloader to get back all the functions that will be lost when unlocking), because during the unlock process, you erase DRM data and that means (as far as I remember): no location sharing on stock SMS app, no xreality, no warranty and also I've heard that the camera possibilities are much more limited than on locked bootloader... and maybe there are more things that you lose because of unlocking BL.
I'd recommend disabling all the bloatware that disturbs her. Well, you won't be able to disable all of them, some has "Disable" button greyed out but most of the bloatware CAN be disabled. Also I'd recommend flashing stock, non-branded ROM.
All my previous Xperias had unlocked bootloaders but now my new Z3 Compact has it locked and I'm definitely NOT planning to unlock it. There's too much to lose after unlocking BL, that's my opinion.
The biggest thing for me that brought me back to a stock (de-bloated) ROM was the camera. Quality is so poor. It's really night and day difference. Even worse, the camera relies on AOSP services and you end up with a "fish-eye" distortion. Photos with anything vertical look like they are curved and that's something i simply cannot live with. Quality of photos, maybe. Distorted photos, nope. If this were to be fixed.... I'd be right back to AOSP.

Need Your Help!!!

Hey Guys, I have a question.
I had no idea about DRM key loss and its results untill I unlocked my c6603
Now everything seems OK except camera. When I take picture, they too noisy.
Quality doesn't satisfy me. Do you know any solution to increase the picture quality?
P.S DRM restore tool doesn't seem to work for me(

if you had backed up your TA partition just before you unlock bootloader for first time ,then you could restore that backup using TA backup/restore tool and get your DRM keys back, this is the only way to re-enable sony noise reduction system.
but for picture quality you can use 3rd party apps in market like camera fv-5 but don't expect miracles.
press thanks if you find this helpfull.

How to fix camera after root?

I rooted my Xperia XZ1 compact. Now the camera is very grainy. How can this be fixed? I didn't backup DRM keys before rooting.
You can't. You lose some camera features after you root without restoring the DRM keys.
I've also rooted the phone but didn't do any backups of anything. I've noticed no difference in the camera quality before/after rooting. What did I lose? I've also read about photos turning green or something, what is that? What are DRM keys?

You will have lost some quality in your photos and lost access to certain features. What does your service menu/security screen look like? https://www.xda-developers.com/sony-xperia-android-pie-unlock-bootloader-drm-fix-camera/

Quick question regarding root on XZ2(C)

Is it possible to root the stock rom without losing functionality on the latest firmware?
If so, can you point me to a guide?
I don't care about custom roms, weird mods or unlocking the bl or doing anything too crazy. Just plain old root to debloat and use adblocker + firewall.
I'm going to buy either the XZ2 or the Compact version soon. I assume the procedure is the same.
Sooo, this is what I was able to find out by googling and lurking XDA extensively.
The phone can be unlocked but you lose all kinds of sh*t by doing so, because on this one unlike the XZ1 you can't backup the DRM keys. It is still a mistery to me as to what gets lost. I heard camera quality, camera filtering, video effects including slow motoion, and audio enhancements. Rumor has it that you may lose the camera altogether if you unlock.
There also doesn't seem to be a way to trick the device into thinking it's unrooted or to bypass the DRM keys like on the XZ1 (drmfix). So once you lose these keys there's no turning back (cue dramatic music)
So, unlocking the device if you want to keep the stock camera working should not be done
Using temp root exploits is doable on some old firmware, but if you modify the system partitions the device will lose DRM keys forever anyway (so what's even the point?)
Also
The phone cannot be relocked once unlocked, just like the XZ1
Camera will work again on LineageOS
But camera quality is dogsh*t on LOS and lacks all the fancy slow motion effects
And you cannot get any of that back
IS THIS LIST CORRECT?
