What does the functions do that is lost when unlocking the bootloader?

And do they make a big difference to the phones functionality?

As i gather, you lose X-Reality and Bravia Engine functionality.
If you backup your TA I think you could restore them and relock bootloader.
Also if you're on 4.2 you will break your camera. 4.3 and up fixes this problem.

Hit thanks If I helped you

I saw someone post that if you unlock on KK (4.4.2) you wont lose X-Reality and Bravia.
Only the captured images are slightly different...

No, to me they don't but my only concern is the loss of quality in pictures, this is the only thing which stop me from Unlock my Bootloader.

Backup TA is just a Backup of your DRM keys, to not lose them permanently, so one day you want your phone back to Stock you have them and you can restore them BUT they are lost permanently when you Unlock Bootloader and they are not working, this do not effect the functionality of your phone but they affect the quality of your pictures. So apparently something they do.

Wait a minute, first you say they are not lost permanently by doing a backup, and then you say "you can restore them BUT they are lost permanently when you Unlock Bootloader and they are not working"

wtf?

Just a language barrier I think

You can backup your TA (Which contains the DRM keys)

If you unlock your bootloader you lose DRM keys

If you restore your DRM keys by restoring your TA you relock the bootloader

Basically its not possible to have DRM keys on an unlocked bootloader
