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).
image and explanation
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?
Same experience here. On the website, the left side never fully matched either shade on the right side to me, appearing closer to the bottom but always somewhere in between most of the time. But when I view the screenshot linked above in my mobile app for Lemmy, it looks a lot closer to the top than the bottom, but varies a bit based on how much I zoom in (almost like moire patterns).
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
