By looking at FUS release notes you should be able to tell. (look for Emergency image version or Bootloader version)

https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus-rn-20.html

For example, here is what FUS 2.0.0.0 release note says

Cisco 8510 Wireless Controllers

Emergency image is upgraded to 8.1.133.7 Updates RAID firmware to 20.13.1-0200

Your 8510 got FUS 1.1.0.0, see below (table 1)
