Photography under fluorescent lights and color banding. Any way to fix it?

Any Nuke folks out there?

Can anyone pinpoint to some possible ways to tackle this problem or at least made it less noticable?

I got that this is related with fluorescent lighting. Fluorescent lights flicker, they change both intensity and color 50 or 60 times per second (depending on where in the world you are) and camera settings and its shutter speed has to be matched with their frequency.

But I have this footage to work with, no reshoot, it's already 3D tracked shot and this ugly beast is the only one left to tackle.

I am still slightly novice with Nuke so any help would be appreciated.
What nodes to look for, maybe links or whatever information would be cool. There is some hurry in all this shit around this shot that needs to be tackled

I have strong suspicions that this is total crap and can't be fixed in Nuke.
Maybe some wall model with similar texture and rendered separately could be better solution since we have tracked camera?

I am not a comp guy, don't know what is possible in Nuke in such situations.

Hey, best bet would be a wall projection with a tracked camera, paint up a frame of how the wall should look, project it onto a card/geometry in nuke.

The footage looks like terrible quality though...

I somewhat compressed image so it uploads here.

Footage is terrible anyway but works for client. Good case where "fix it in post" didn't work
Tried wall scenario. Its better but comes with its shortcomings, tracking isn't perfect either. Kinda works but far from perfect.

Our Flash/2D artist somewhat places his Flash graphs to hide this horrible thing as much as he could

There's also the Furnace DeFlicker node, which may work to some extent.
