    I think modern graphics cards are programmable enough that getting the gamma correction right is on the devs now. Which is why its commonly wrong (not in video games and engines, they mostly know what they’re doing). Windows image viewer, imageglass, firefox, and even blender do the color blending in images without gamma correction (For its actual rendering, Blender does things properly in the XYZ color space, its just the image sampling that’s different, and only in Cycles). It’s basically the standard, even though it leads to these weird zooming effects on pixel-perfect images as well as color darkening and weird hue shifts, while being imperceptibly different in all other cases.

    If you want to test a program yourself, use this image:

    Try zooming in and out. Even if the image is scaled, the left side should look the same as the bottom of the right side, not the top. It should also look roughly like the same color regardless of its scale (excluding some moire patterns).

      On that web page, the left side is similar to the bottom, but on Lemmy, the left side looks purple like the top right. The bottom right appears grey to me. Is that supposed to happen?

        On, Lemmy the image is definitely not producing the same effect as on the website. On the phone, I can do incremental zooms of the page. If I zoom very lightly there is a sweet spot where it looks exactly like the top, but fully zoomed out(the default view) it is looking the same as the bottom. Clearly there is a problem with scaling the image unlike what /u/AdrianTheFrog said
