M51 display less bright than M31

[PKDDKP]

Hi - I received a M51 from Amazon and then had to get it replaced because the charging port was faulty. The new model of M51 which was delivered seems to have a lower brightness than the M31 which I also own and is new. Side by side comparison clearly indicates that while the M51 has crisper display for HD videos on Netflix,  the overall brightness across all screens and apps is lower than the M31. How is this possible ?

I have checked most display settings and set them to maximum, and all adaptive display settings are disabled. Is this a M51 issue or is my model faulty ? Please advise on some fix for this if anyone else has also felt the M51 brightness is lower . The sAMOLEDPLUS should not have a lower brightness than the M31.

Now brightness controlled by Google intelligent Machine learning...

Yes but how is it consistently lower than the M31. I have checked in low light and bright light conditions.

[Dr_Interchupipi]

Nits under light is less bro in m51 ..and that is good only because less chance to get display burn in..and under light m51 nit is 373 where m31 is 420 so obviously it's bright

Okay. But even in no light condition, that difference is expected ? I was thinking I didn't notice this with the first model that was delivered to me, but perhaps that's an inaccurate memory of it . I thought a device issue and almost going for yet another replacement. I guess you would say that won't help?

Bro .. now adaptive brightness given by Google os .. as Google minimize it by intelligent machine learning AI .. not only m51 .. in s9 ,note9 also .. I am using s9 and it's lower than previous now .. m31 have fixed nits so you can't compare like that
