Yes: Ive had a Long Ranger (The Newcastle NSW built ones) in a Nissan WD21 Pathy and it usually took 135+ litres on a 140L spec day-to-day, with the light well and truly on.
The car's OE fuel gauge references from the floor level of the tank NOT tank volume: it measures the height of the fuel remining in the tank so with a bigger tank, there is more stored fuel above the 'high tide' (full) level the gauge reads. So, the gauge will show 'full' for longer (it won't move), and your low fuel warning light will come on with a larger quantity of fuel remaining than with an OE tank. Like, as much as 20+ litres
A few percent from spec doesn't worry most people - temperatures and retail fuel pump calibration issues can alter the "actual" volume you think is being put in the tank. My Pathy had 19-20L remaining the instant the light came on - measured by draining as part of a vehicle preparation regime, not by guessing. If this concerns you - it interested me for remote area travel - maybe you could do the same, just so you know what the actual level is when the light comes on.
My current Hilux (OE tank) has at least 10L remaining when the light comes on - I can drive at least 70km without running dry. So you MAY have had that much in yours when you arrived at the workshop[...but who re-uses old fuel?
Who fitted yours? I'm sure LR specifies the tank be filled at installation to check for leaks etc
Tactfully said, maybe you could live with this tank a little longer before expressing your "shock" at Long Ranger's decades-long history of quality tank supply.
Let us know how things pan out over the next few tanks!

I agree with GTC about Long Ranger's reputation. When they say "140 litres" I would confidently believe that is the liquid fuel capacity from a bone-dry tank to full. Trying to determine the tank capacity by calculating from driving and consumption is very inaccurate.
Rcam, if you really want to verify the tank liquid capacity you would need to drain the tank via the drain-plug then accurately measure the quantity of fuel to fill the tank. Whilst doing this you would also be able to determine how much fuel is required to extinguish the low-fuel lamp and also the gauge indications as the tank is filled.
In my own case as a test, I continued to drive after the low-fuel lamp came on until the engine starved. This was about 50km so I now know how much reserve I have below "empty" indication.
In the other direction, with an absolutely full tank I drive about 100km before the gauge starts to move down from the top stop which is satisfactory. The overall calibration is therefore fairly reasonable but I believe it more important to have the gauge and lamp most accurate at the lower end.
Incidentally, it was necessary to have an automotive engineer verify and issue a vehicle modification plate for the tank installation. I understand that it was his requirement that the tank be filled with fuel as part of his inspection. I would expect that Long Ranger would also specify this as part of the installation. If, as in my case, this were done the fuel fill would verify the tank capacity.
