(I guess you mean "shrinking"?)

Theoretically, if your your display is configured properly, the 
/background/ of the thumbnail should look different.

Let me re-iterate the facts here:

- It is perfectly normal for the left (double-width) strip to /look/ 
more linear than the right (single-width) one.

- It is also perfectly normal for typical image processing software to 
report the "RGB values" or "greyscale values" of the left strip as 
near-"linear" (something like (0;0;0), (25;25;25), (51;51;51), 
(76,76,76), ... (255;255;255), or 0%, 10%, 20%, ... 100%)

- It is also perfectly normal for typical image processing software to 
average the black-and-white striped background to the same value as the 
middle swatch in the left strip when creating a scaled-down version of 
the image.

- It is however also perfectly normal for the original black-and-white 
striped background to look more like the middle swatch in the /right/ 
strip when squinting your exes.

- The black-and-white stripes of the original-size image background 
/inevitably/ generate a physical light intensity exactly halfway between 
black and white, i.e. /truly/ 50% white.

=> The left stripe typically /looks/ linear, while the right strip 
typically /is/ linear.
