THIS ONLY WORKS FOR CERTAIN DEVICES!

I actually found this out by accident, when i was flashing my stock rom on my s6.

Thing you will need:

Galaxy s6 Engineering bootloader. i don't think i can link this here, easily found with Google
Arter97's flashable zip with a custom bootlogo. http://arter97.com/browse/exynos7420/bootlogo/
Odin 3 http://forum.xda-developers.com/showthread.php?t=2711451
TWRP for s6 https://twrp.me/devices/samsunggalaxys6.html
Stock s6 firmware http://www.sammobile.com/firmwares/

Steps:

1. YOU MUST BE ON 5.1.1 FOR THIS TO WORK

2. Find and flash your engineering bootloader (my model is g920f, bootloaders for other devices are also available i think) by running odin 3 as administrator, booting your s6 into download mode by holding VOL-DOWN + HOME + POWER, untill you see a warning, hit VOL-DOWN. Then plug your s6 into your computer. odin will detect your s6 after the drivers finish installing. click on the BL Button, select the md5 file with the bootloader. Odin will check the md5sum of it. click start and let it do its thing.

3. Boot your s6 into download mode again. reopen Odin. select the AP file with TWRP. click start, and let it do its thing.

4. Unlock your s6. let it connect to your computer. place the bootlogo zip file in the root of your s6. Boot into Recovery mode by holding VOL-UP + HOME + POWER, untill you are shown a Team Win logo. tap install. tap install from sd card. sellect the custom bootlogo zip. install it, and tap reboot phone

5. When your phone is rebooting, you should see a custom bootlogo. if not, restart the process.

6. Boot your s6 into download mode again. connect it to your computer. open Odin. click on AP and select the stock firmware. it will take some time, but when it outputs Leave CS. click start. after the process is finished, you should have KNOX:0 And a custom bootlogo!

IMPORTANT
: Store your file PARAM.BAK from the root of your s6 somewhere safe, in case you want to roll back later

PLEASE NOTE: the flashable zip file with bootlog should work on all exynos devices, but not everyone has a leaked bootloader. if flashing it without the engineering bootloader, the KNOX will be tripped, and therefore, no Samsung Pay, or any Knox reliant service
