Lens Correction

Using the a7R IV, I kind of wish the jpegs came out to a smaller size. I have been thinking of just using Capture One to process my raw files to jpeg. However, I have noticed that the lens profile from Capture One does not match exactly what the out-of-camera jpegs have. Can anyone weigh into which is actually more of a correct profile? I would assume the ones coming from the camera would be but maybe Capture One is? Also selecting the specific lens or manufacture profile doesn't make a difference. To my eyes, it appears the OOC correction is more accurate. I also saw this happen with the a9 and a7 III, using Windows and Mac.

  I think the only way of judging which is a more accurate correction would be to take some test shots and compare them. So shots of something where distortion would be obvious, like a brick wall, taken carefully with the camera level and absolutely straight on to the wall.

  I was thinking I’ll likely have to do that. It seems odd to me that for me, the manufacturer profile selected doesn’t seem to change the distortion from the specific lens. Everything I have read said that the manufacture profile should match OOC.

  I've noticed the same on my Fuji XS-10 + 16-80mm F/4 

  Same for colour profile. The film simulation is properly detected and while far better than other viewers* the result on screen (or exported to JPG) is still noticeably different from the OOC.
