sequia version

hi dear
I have a Sequoia and I want to know what version it is. I don’t have a sunshine sensor either.
On the RGB images, the EXIF ​​version is 0.210. And there is no value in other bands.
Do I need a target for corrections?
The firmware version of the camera is 1.5 and the version of the camera itself is 1.4.1
Model 207-16ilia
