But did they or didn’t they run the appropriate checklist? I’m confused.

DId you hear the one about the jurisprudence fetishist? He got off on a technicality.
Re: IFE and Recirc Fans
One can never be sure based on a report that may not be entirely representative of what happened. But the thrust reduction altitude is relatively low and the report does sound as if the captain reached up and shut off the bleed air from the APU, which likely had no adverse effect and had a lot of beneficial effect.
This compared to the long process that can come with memory items and checklists(which can still be performed) that involve donning oxygen masks and going through more than one path in order to find and then isolate what the problem is. All while smoke is pouring into the cockpit and mountains of Colombia patiently wait to claim another airliner with a distracted crew.

C-FKIW, a Boeing 737-700 operated by WestJet Airlines was conducting flight WJA175 from
Edmonton International, AB (CYEG) to Vancouver international, BC (CYVR) with 5 crew members
and 128 passengers on board. During the climb to cruising altitude, the flight crew noticed a
burning smell in the cockpit. The flight crew contacted the cabin crew, who also confirmed there
was a similar smell in the cabin. The flight crew made the decision to return to CYEG. A PAN PAN
call was made with ATS and airport rescue and fire fighting (ARFF) was activated. An uneventful
landing was subsequently completed, and ARFF met the aircraft on the runway to perform an initial
inspection. After determining there was no indications of a fire, the aircraft taxied to the gate were
the passengers and crew deplaned.
Subsequent investigation by company maintenance found an unserviceable cabin air recirculation
fan. The fan was replaced, and the aircraft was returned to service.

Sep 20, 2022 update: One could immediately turn off the utility switches and go check out the problem while the other pilot prepares for a diversion. Then discover that the galley smoke is gone.
D-ABYK, a Boeing B747-8 aircraft operated by Lufthansa German Airlines, was conducting flight
DLH403 from Newark Liberty International Airport, NJ, USA (KEWR) to Frankfurt Rein-Mein,
Germany (EDDF). While in cruise flight, the cabin crew reported an electrical smell with light
smoke in the forward galley to the flight crew. The flight crew declared an emergency and initiated
a diversion to Boston Logan International Airport (KBOS) where the aircraft landed without further
incident.
Maintenance personnel conducted an inspection of the aircraft and identified an espresso machine
in the forward galley as being the source of the electrical smell and smoke.

Re: IFE and Recirc Fans
Looks like the recirc fans again.......
N880BJ, a Boeing 777-300 operated by American Airlines, was operating as AAL754 from
Philadelphia International Airport, Pennsylvania, USA (KPHL) to Charles de Gaulle/Roissy Airport,
Paris, France (LFPG). During cruise, the cabin crew detected fumes/odour in the area of the 2R
and 3R door. The odour was described as an epoxy smell that worsened as the flight progressed.
The flight crew contacted Moncton ACC and requested to return to KPHL due to a mechanical
issue. The flight crew accomplished the associated QRH items, and cabin crew checked overhead
bins and lavatory trash bins for the source of the fumes/odour, but the source could not be
determined. When the fumes/odour began to permeate the entire aircraft, the flight crew declared
an emergency while in Canadian airspace and diverted to Bangor International Airport, Maine, USA
(KGBR) where they landed without further incident.
In KBGR contract maintenance could not determine the source of the fumes. A disinfectant
cleaning was completed in the cabin between seat rows 10 thru 19.
During the maintenance ferry flight to KPHL the odour was again present in the cabin between
rows 10 and 19. Maintenance personnel in KPHL replaced the lower recirculation fan and both the
left and right air purification filters and the aircraft was returned to service.
