As far as it actually matters (which is not much), you could disassemble the meter and look at the markings on the PCB, as well as look at the general design and layout of the internal components and any markings on the inside of the case. If an OEM is involved, then they may leave some of their signatures behind during manufacture.

Perhaps, but there are different levels of OEMing.  One one hand you may have a company that says to another "we like your product, put our name on it and change the holster to green and we'll retail it".  On the other, you may have one that says "here are the design files, can you make it for us exactly as we specify?".  So Brymen and Greenlee have one relationship, Apple and Foxconn have another.  What Brymen and Fluke have, IDK.  I can't find financial information for Brymen, so I've no idea how big a player they actually are, nor who has invested in them.

I don't know if anyone cares, but here are my notes on some of Brymen's OEM models for Greenlee and Amprobe.  Take with a grain of salt - there are likely errors.  In fact, if anyone has corrections or additions I'd welcome them.  Of course one of the big differences between Greenlee and Brymen (aside from Green vs Red) is the warranty: Greenlee is lifetime, Brymen is typically 1 year (maybe some are 3 years?) and from what I hear is difficult/impossible to get handled if you're in the US.

  - Greenlee DM-200A = Brymen BM251 (Greenlee has backlight)
  - Greenlee DM-210A = Brymen BM252 (Greenlee has backlight)
  - Greenlee DM-510A = Brymen BM257 (Greenlee is still 8A as of Jul 2023, so it's not a BM257s)
  - Greenlee DM-820   = Brymen BM859 (note: *not* BM859s)
  - Greenlee DM-810A = Brymen BM822s                       
  - Greenlee DM-820A = Brymen BM827s
  - Greenlee DM-830A = Brymen BM829s
  - Greenlee DML-430A= Brymen BM525s
  - Greenlee DM-860   = Brymen BM859s (Extech MM570A)
  - Greenlee DM-860A = Brymen BM869s

  - Amprobe AM-270   = Brymen BM817a (also identical to BM817s except for fuses and protection rating according to datasheet/manuals)

  - Amprobe AM-140-A = BM857a (*very* minor difference in manual range capacitance) and BM857s (except A limited to 15A on AM-140-A, 20A on BM857s), also Extech MM560A. Maybe BM857.

  - Amprobe AM-160-A = BM859CFa (*very* minor difference in manual range capacitance) also BM859s.  Also Extech MM570A and Greenlee DM860 (not Greenlee DM860A).  Maybe BM859.

  - Amprobe PM55A    = Brymen BM27s

I should also add that the Flir DM64 and DM65 are OEM equivalents of the Brymen DM235 (it seems that the DM64 and DM65 are themselves identical except that the DM65 is packaged with slip-on alligator clips!).  Flir's US website is still selling the DM64 for $50 (only shipping to the USA as far as I know).  Since the last time I looked at Flir's website the number of multimeters has been reduced significantly.  Don't know if that's a temporary thing or the company shifting focus?

J-R:
My point of pointing out the Fluke 373 "Assembled in China" was that those weren't made in Taiwan, which was previously presented as proof that they were made by Brymen.  Just showing a box label is also not such proof.

So far we've had blatantly obvious proof that Brymen makes such and such products for another company, but proof for Brymen making things for Fluke is not at the same level.

What level of proof you choose to accept is up to you.  However, as a geopolitical but topically relevant question, if Brymen assembled the product at their plant in Taipei but shipped some or all of them to Shenzhen (for example)either to be sold in mainland China or to be repackaged and further exported, how would you expect them to be labeled?
