Setting an ISO minimum of 400 seems to have no effect in Auto ISO

If I set my ISO speed range to a minimum of 400 it seems to have zero effect when shooting in Auto ISO mode as you can see in the screenshot. It still picks ISO's below 400.

Also, I have HDR PQ enabled which has a base ISO of 400 and it's not giving me any indication of this. But if I switch to C-Log 3 then Auto ISO won't go below 800 which is the base ISO for that, and if I manually try to select anything less it indicates it with an "L".

So, two questions:

1. Shouldn't Auto ISO honor my ISO speed ranges?

2. Shouldn't HDR PQ mode behave like CLog3 mode and limit the minimum ISO to the base ISO, and indicate the lower ISO's with an "L"?

Its silly but only the MAX settings apply to the Auto portion. There is no minimum for auto not like Sony or perhaps other manufacturers,

The ISO speed range values are only used when using manual ISO
