Ok, so what is the state's definition of "conspicuous"? Who has priority as far as allowing/not allowing guns. Scheels says you can CC, but the mall says you can't. Who is the one you have to abide by?
You've got a few questions wrapped up here.
First, "conspicuous" is... weird yes. LB352 was/is to address these issues.

Priority as far as allowing weaponry is a fun question. I am not a lawyer so take this as you will.
Within Scheel's and it's curtilage you are probably fine by following Scheel's policy.
The problem is that you can't GET TO Scheel's property without crossing 'generic owned by the mall custodian' property.
There is some interesting caveats to this.
I had a post a while back about a little strip mall that had no-guns signs at the entrances to the parking lot. In my mind, that makes things pretty clear.
For Scheel's this is more difficult, it's a HUGE area etc.
Buuuuttttt...
Lets go with say, Lefties Snausages House. This business doesn't allow concealed carry. You are perfectly fine to park in their drive way, walk up to their door, see the no-ccw sign, turn around and go back to your vehicle. You've not broken any law (AFAIK).
With Scheel's ... I... am not really sure if it's connected to other stores or only has it's own PRIVATE entrance/exits... but... I would assume that as long as you only entrances/exits that are Scheel's only, you would be fine. You are making use of public parking, etc.
If signs are posted at the entrances/exits of all of the parking lots for the mall area... then it might become a bit more weird. I imagine legally you'd still be fine (public parking space argument possibly ?) ... but that would bring us back to the property rights vs 2a kind of stuff that was heatedly debated here concerning LB335 hehehe.
