After buying an used 5dm3 I noticed the LCD has a purple tint specially in comparison to my 70D.
For this test I took the picture from the 5Dm3 (latest firmware), took the SD and plop it in my 70D and you can still tell the purple cast.
Once I put them in my computer the images look fine.
It's just on my 5Dm3 lcd.
BTW both cameras have the same Picture Style set to NEUTRAL.
Is this normal???
