Mission 1 - EXPS=1 discrepancies

[RikshaDriver]

When enabling EXPS=1 (QR Code works but is not documented for Mission 1) the ISO values are vastly different than what Camera Info display is showing.

For example, Camera Info will show ISO 2100, whereas via EXPS=1 it is showing ISO at 5800

I'm trusting the standard in built feature. Consider EXPS obselete. EXPS is using older techniques and is not aware of the dual gain characteristics of the new sensor.
