New big issue - Colors export change with size

Hi there,

Folowing my previous thread, here's a new way to see the issue :
If you export with exactly the same settings, but dimension, you will have different colors results

Here's a tiff 16 bit export at 100% size
http://img4.hostingpics.net/pics/354443100.jpg

Same exported at 33% size.
http://img4.hostingpics.net/pics/4627815633.jpg

The thing is, the 33% size looks exactly as what you see in the viewer at 33%
which is not correct.

The 100% is correct, but yon only work on it with accuracy if your viewer is at 100%

  Here's another one :
  
  Same settings except size reduced at 33% on the left one

  So to resume this unacceptable issue :
  If you downsize, in the viewer or when you export, a more than 3200 ISO photo, C1 shifts colors 😕
  And the more the ISO are high, the more the colors shift is important.

  I have exactly the same problem.
  If i zoom a .raf pic the color changes and if i export the .raf to jpg the color change again. Booth chances are in the same way like yours.
  But, i have this effect, till now, just with Fujifilm .raf files. With Nikon .nef files it seems to be ok.
  I'm testing CP1 right now. As i use both format on a very regular basis this needs to be fixed. Otherwise CP1 is useless for X-T2 user which would be a pity because i like CP1.

  Strange. But is this actually a color change or a luminance change ? The samples at 33% just appear to be darker.

  Actually, it depends on what part of the image we observe. In some areas the image appears darker and in others there's an actual color shift.
