I have an old stock of Soviet precision metal film resistors S2-29V that I use as a reference. Compared them to Dale's 5 ppm resistors and there was no difference in the measurement area. Statistics and various practices indicate that they are most likely linear, as far as I can currently measure.
But in general, each sample of any resistor and capacitor should be tested individually before it is used in critical locations.

IMHO those, as Demian wrote: Vishay doesn't even publish linearity info on the Bulk Metal resistors. https://foilresistors.com/docs/63140/var.pdf
In the old days there was the Alpha Core as also none inductive as in a black plastic block.
As mentioned:
At that, negligible capacitance/inductance of foil resistors (when compared to wirewound resistors) significantly reduces
probability of self-excitation or "ringing" of amplification circuit.This is why Bulk Metal® foil resistors are such a good
choice for low-noise applications...

MELF resistor from Token Electronics as none inductive as RFM series

Yes, in many cases.The better resistor is two resistors in series instead of one.
Also, by connecting four identical resistors in a series-parallel circuit instead of one and comparing the results, we can understand whether the resistor is linear or not.
